Urmi Poddar on 2024-07-15 23:35:37 Dear TRY team, I download and used TRY data for one of my studies, and I am about to submit the results of this study for publication. As you probably know, many journals require authors to publicly share the raw data used in their studies. Therefore, I wanted to know what TRYs policy on secondary data sharing is? Specifically, I am allowed to share the raw TRY data I used on another data sharing platform, such as Dryad? If the sharing of raw data is not allowed, are there any restrictions on sharing processed data (i.e. TRY data that has been filtered and summarized by me)? If it matters, my request ID was 25355 and I did not request or use any restricted TRY data.
Jens Kattge on 2024-06-10 08:45:11Dear Jelyn, it would be good to add a list of these references to the appendix (not supplementary material) and cite this appendix in the main text. Global Ecology and Biogeography recommends for citations to data sources: Some studies (e.g., meta-analyses) use data drawn from multiple published sources. If these sources are not otherwise cited in the main text, they should be listed in one or more appendices with titles similar to the following: “Appendix 1 – Data sources”. These data appendices will be printed in the main paper (so that citation indexing services will capture them), but in a reduced font. These appendices should be cited in the main text (e.g. “A list of the data sources is found in Appendix 1.”). (see https://onlinelibrary.wiley.com/page/journal/14668238/homepage/forauthors.html).
Jelyn Gerkema on 2024-06-07 14:03:53Dear TRY team, I have used quite a large portion of the TRY database (27 traits and all available species) to impute missing values and therefore have 383 references that I need to cite. Would it be okay if I refer to these in the supplementary material of the paper instead of in the main text? Kind regards, Jelyn
Jens Kattge on 2024-05-21 16:03:35Dear Xu Dexiang, According to our internal documentation, your requests number 33774, 33776, 33777, 33779, and 33780 have been successfully submitted. However, you are asking for public and restricted data. In this case, it takes two weeks to get agreement from owners of the restricted datasets. Therefore, from my point of view, everything looks fine. With best wishes, Jens
Xu Dexiang on 2024-05-20 04:53:33Hello, dear TRY team, we still unable enter the species choices normally, I sent an e-mail to Prof. Katte and Prof. Boenisch. The attachment contains the trait selection we hope to obtain, sincerely hope to receive your reply, thank you so much. Wish you all the best.
Jens Kattge on 2024-05-17 09:06:29Hello Xu Dexiang, Im sorry for the problems. Please try again. I think it should work. Please let us know if the problem persists.
Xu Dexiang on 2024-05-15 15:47:57Hello, dear TRY team, we are trying to applying for some traits data, after we made the trait selection, we selected continue without species list, because we want to collect as many species as possible and then the continue screen kept getting stuck, and then it came up with with the error: "The proxy server received an invalid response from an upstream server. The proxy server could not handle the request". These data are very important to us, and we hope to get your help, looking forward to getting your suggestion and help, thank you so much!
Nelly Bergounhon on 2024-04-26 11:28:51Hello, Dear TRY team, I am slightly confused on the nature of data found in the "frost hardiness database". I cant understand if the values are about buds or leaves. I am also slightly confused by the meaning of "maximum", "high", "low" in the ValueKindName column. Do "maximum" and "high" refer to the the temperature at which 100% of the buds die ? Does "low" refer to the temperature at which mortality start to be observed ? Thank you for any help you can provide, Nelly Bergounhon
xianghua li on 2024-04-12 09:03:40Hello, Dear TRY team, this is regarding the last question we asked, we found out that it was caused by our operation problem and it has been solved. We apologise if this caused you any distress and thank you.
xianghua li on 2024-04-11 05:57:08Dear TRY team, Hello, we applied for some open data of species and traits, which has been approved, but clicking on the final data download link does not open, and attempts to change several computers and networks failed, with the error: "The proxy server received an invalid response from an upstream server. The proxy server could not handle the request". These data are very important to us, and we hope to get your help, thank you!
Jens Kattge on 2024-04-04 16:04:59Hello, Emmy. Please send me the file with the dataset so I can help you. Jens
Jens Kattge on 2024-04-04 16:01:59Hello Evan, unfortunately, I cannot provide any help with respect to the traits you are looking for. We may have some of these data in the TRY database, but for none of these traits, many.
Emmy Sköld on 2024-04-04 11:11:36Hello Gerhard, I am doing a meta-analysis for vegetation change after rewetting in peatlands based on functional groups. Therefore, I have been trying to access species list in regards to trait 815, Root morphological adaptations: aerenchyma. However, when I open the dataset, I do not understand the given information in regards to if the species has an aerenchyma or not. I was wondering if you have any idea of what could be the problem? Thank you for any help you can provide in advance. Emmy
Evan Peters on 2024-03-18 16:46:12Hello Gerhard, I just came upon the TRY website recently. I am doing a meta-analysis for Plant based cosmetic ingredients, and am as a result collecting as much data as I can regarding the plant sources of these ingredients. I was hoping you could point me in the right direction for some of the following values that are of use to me in my modeling of environmental impact: - cultivation practices; such as farming practices, fertilizer utilization, pesticide use - industrial yield information: how much fruit/seed/flower is typically harvested per plant or per hectacre etc. - seed/flower oil content: how much oil can be extracted from the seed or fruit or flower of the plant Data such as these are not easy to come by. I have had some good success using the seed information database. But I am hopeful I can get more information from TRY if I focuse my search. Thank you for any help you can provide. Evan
Gerhard Boenisch on 2024-03-14 13:43:46Dear Emma - If the outfile contains less than 1 million lines, you can open in Excel as tab delimited text file. If it looks funny after a few lines, something has gone wrong and I personally would start from scratch. All our files are quality controled, so it is rather likely, something happened on your site.
Emma Underwood on 2024-03-14 13:28:19Hello, I have queried and downloaded data for 1 trait (3116) for 15 species. When viewing the txt file downloaded in xls the formatting looks odd below row 29, should I ignore these data? it involves datasets 94, 159 and 249
Gerhard Boenisch on 2024-03-12 10:52:14Dear Micah - All units we have are included in the output of data requests. You can however not find them in the Data Explorer. Gerhard
Micah Pavlidis on 2024-03-12 01:07:59Dear TRY team, I have tried to find a description and units for the "Plant reproductive phenology timing" trait, with no luck. Could you please define this trait for me? I am having a hard time interpreting the results of my analysis without knowing the units. Thanks very much for any help you can provide. Micah
Gerhard Boenisch on 2023-11-17 08:49:46Dear Benjamin - you will haveto wait for the next TRY version for the update to be available . But yes, there isa version control
Benjamin Lewis on 2023-11-16 23:55:30Also, is there version control? Say we upload the data but then need to add something later, is that possible?
Gerhard Boenisch on 2023-11-16 22:05:48Dear Benjamin - after the actual upload you can add the custodian, deputy qnd contributors during the process
Benjamin Lewis on 2023-11-16 22:02:05Hi, Ive been tasked with uploading some data here that a different researcher actually collected. Before proceeding with the upload, I an curious if there is a way to make sure said individual is the one who gets the credit for the data. Thanks.
Hsiao-Hsuan Chu on 2023-11-08 00:54:16Dear Gerhard, Thank you so much for the help, the settings for request 29702 are correct now. Many thanks!
Gerhard Boenisch on 2023-11-07 10:12:39Dear Hsiao - I have removed the second author from ypur request and contacted him, if he had tried to submit a request that got lost. Can you please check the settings of request 29702, if the settings are correct?
Hsiao-Hsuan Chu on 2023-11-07 01:20:15Dear Gerhard, Request 29702 and coauthor Xueqin Yang. Many thanks.
Gerhard Boenisch on 2023-11-06 11:55:00Dear Hsiao - which request, which coauthor?
Hsiao-Hsuan Chu on 2023-11-06 06:22:09Dear Try team, Thank you for the mega effort in creating this database. Over the past week or so, I have been seeing an additional coauthor listed in my request for data. I do not know this author at all and I have no ways of removing them from my request. Best regards.
Gerhard Boenisch on 2023-11-01 10:18:15Dear Jiajia - you have started the request, but not asked for the data yet. To do so, go to your Request PI Center (from Data Portal, Request on Hold), open and finish it by following the web sites until you do not see a button any more
Jiajia Zheng on 2023-11-01 10:12:11Dear TRY team, I have requested to download these data yesterday (Number: 29733), why the data is not released yet? Please assist me in resolving this issue. Good luck!
Gerhard Boenisch on 2023-10-16 10:47:39Dear Samuel - Your dataset is scheduled to be included in the next version of TRY which will be 7. What you see, is only a placeholder. We are currently working on the next version. Sorry it takes so long, but new versions are a lot of work.
Samuel Flake on 2023-10-13 01:40:30Hi Jens and Gerhard, I was just checking on a dataset I uploaded a little bit ago (DatasetID 777), and it looks to be empty on the data custodian center. Is it in fact empty? And is there anything I can do to help get the data back up? Thanks so much! Sam Flake
Gerhard Boenisch on 2023-09-25 12:25:35Dear Zhang - How can someone publish data with only AccSpeciesIDs? How long is the list? Can you send it to me by email? I might be able to provide you with the names.
Zhang Ran on 2023-09-25 11:48:46Cause now I have some data from published paper, but this data have only the AccSpeciesID but no species name. I matched the AccSpeciesID from the species list I can download from this website but most of them can not be matched. So I want to know how to get the species list information used in that paper (for TRY 5)
Zhang Ran on 2023-09-25 11:48:39Cause now I have some data from published paper, but this data have only the AccSpeciesID but no species name. I matched the AccSpeciesID from the species list I can download from this website but most of them can not be matched. So I want to know how to get the species list information used in that paper (for TRY 5)
Zhang Ran on 2023-09-25 11:48:34Cause now I have some data from published paper, but this data have only the AccSpeciesID but no species name. I matched the AccSpeciesID from the species list I can download from this website but most of them can not be matched. So I want to know how to get the species list information used in that paper (for TRY 5)
Gerhard Boenisch on 2023-09-25 11:35:09Dear Zhang - Why do you need the old trait info, if you do not have an old output? If you want data from TRY, simply submit a request.
Zhang Ran on 2023-09-25 11:29:01Thanks for your answer, but how can I have a TRY 5 output? Im really a beginner at this
Gerhard Boenisch on 2023-09-25 11:17:02Dear Zhang - The TRY 5 species list is no longer available. However, if you have a TRY 5 output, it contains all the species information.
Zhang Ran on 2023-09-25 11:09:22How can I download the species list for TYR.v5.0? Cause the current version 6.0 not match my previous data.
Gerhard Boenisch on 2023-09-06 11:50:47Dear Cameron - Sorry, you must provide a list of species.
Cameron Guy on 2023-09-06 03:54:51Kia ora, I am working on a tree fern extinction project. I was wondering if it was possible to extract species by their order (i.e., Cyatheales), rather than manually scraping all of the relevant species out in R/from the species list? Thanks so much
taejun jung on 2023-08-31 05:01:55Following the inquiry below.... I would like to know how to find out the meaning of OrigValueStr values not only for Plant nitrogen(N) fixation capacity but also for other traits.
taejun jung on 2023-08-31 04:58:22Thank you so much for preparing the TRY data. I am trying to receive and use various data, but I have a question. For example, in the data for all species of “Plant nitrogen (N) fixation capacity” data (traitID: 8), the values in the “OrigValueStr” column(This column is ultimately the result of “Plant nitrogen(N) fixation capacity”, right?) are not standardized and are composed of various indicators (numbers from “-1 to 2455”, others, “cyan”, “likely_present”, “variables”, etc. There are many different types). Is there any way to find out what these values mean?
Pan Shengnan on 2023-05-18 09:59:53Dear TRY team, I try to download that dataset again, but fail. The web page still display the file cannot be made available. Best wishes
Jens Kattge on 2023-05-17 12:42:33Dear Pan, we had reached space limit on the server. Now we have resolved that problem and it should be possible again to do download the data. Please let us know if you should still encounter problems. With best wishes, Jens
Pan Shengnan on 2023-05-17 11:52:40Dear TRY team, I am very thankful for your amazing database. I cannot download a database named Imputing missing data in plant traits: a guide to improve gap-filling (data). in TRY File Archive, because the web page shows the file cannot be made available. I wonder how I can download this dataset successfully. Best Wishes
Adam Richard-Bollans on 2023-03-22 10:43:00Dear Jens & Gerhard, Thank you both for your clarification of this issue. The reference doesnt appear to mention/link to any Chinese Traits dataset which might contain this information, but I will try to get in touch with the dataset custodian.
Gerhard Boenisch on 2023-03-22 09:32:44Dear Adam - We have to rely on the custodians of the particular dataset that the provided reference is correct. We standardize and compare the data between datasets to make sure the data are reasonable. With about 800 datastes however, we do not have the man power to check each species mentioning in each publication. Please directly contact the dataset custodian on such matters.
Jens Kattge on 2023-03-22 06:54:06Dear Adam, the reference you mentioned links to dataset 236: Chinese Traits (PI Sandy Harrison). This dataset is based on a measurement campaign across northern China and contains data for 46 traits, mostly characterising leaf attributes, among other leaf emergences.
Adam Richard-Bollans on 2023-03-21 23:15:59Dear TRY team, I am slightly confused about a reference given in the dataset. For example, for trait 677 (Leaf emergences (pubescence, pruinescence, hairs, spines, thorns)) there is an entry for Allium senescens from the Chinese Traits dataset. The given reference is "Prentice, I.C., Meng, T., Wang, H., Harrison, S.P., Ni, J., Wang, G., 2011. Evidence for a universal scaling relationship of leaf CO2 drawdown along a moisture gradient. New Phytologist 190: 169-180". However, this reference makes no mention of this species or emergences of leaves. Is this reference incorrect, or am I misinterpreting something? Cheers, Adam
Gerhard Boenisch on 2023-03-07 09:35:43Dear Erik - Which request are you talking about? We have too many.
Gerhard Boenisch on 2023-03-07 09:34:27Dear Tao - Due to lack of man power, the species information has not been updated.
Gerhard Boenisch on 2023-03-07 09:33:03Dear Sarah - We standardize Lat/Lon and convert it to doubles. I do not understand, if you talk about the Data Explorer or the TRY data output. There are special columns for Lat/Lon in the Data Explorer. The data output is in long table format. Please read the supplied data release notes.
Tao Zeng on 2023-03-04 08:26:03Dear TRY team, I am very grateful for this great database platform, but recently I have encountered a problem. I found that the taxonomic information of some recently submitted species could not be found in the TRY_Categorical_Traits_Lookup_Table_2012_03_17_TestRelease.xlsx released by Categorical traits for the species in the TRY database. I dont know if the species categorical information has not been updated since it was published in 2012, or if I didnt find it. Either way many thanks to the TRY team for their great contribution. Best Regards
Erik Sivan on 2023-02-17 15:29:38Dear TRY team, I am very thankful of your database. Today when i submit my data request i cannot find thr record on the Request PI but my email received the request information. I wonder whether i submit my request successfully. Best Regards
Sarah Tepler Drobnitch on 2022-12-15 05:51:46Dear TRY team, Thanks so much for supporting this amazing resource. The FET database has many traits Id like to work with, but Im unable to find Lat/Long/Alt data within the dataset. Normally, lat, long, etc. are datanames with strvalues, correct? Im not sure what Im missing.
Gerhard Boenisch on 2022-12-01 09:13:44Dear Leonid - There is no interface for this. Send me the information by email please. Include upload and dataset IDs
Hunter Mackin on 2022-11-30 01:05:19Dear TRY Team, I am currently looking to find specific plant traits (particularly 186) to model generalized C3 and C4 grasses. However, Im not quite sure how to filter out all the other non-grass species. I also want to keep a distinction between C3/C4 grasses, but I dont want to introduce bias by choosing only a select few species. Is there an established method to do something like this?
Leonid Ivanov on 2022-11-28 09:14:13Hello! I have published some of my data posted in the database. How and where can I enter publication data?
Jens Kattge on 2022-08-08 07:08:17Dear Eleinis- Many thanks for your comment on the Data on Huber value in TRY. Yes, we would be interested in checking these data in TRY directly. Please contact me for more details!
Eleinis Avila-Lovera on 2022-08-03 00:20:51Hello! I really appreciate all you do to maintain this database. I recently downloaded all the publicly available Huber value (HV) data (trait 171), and after inspection of the datasets that have contributed towards HV, I found that many observation values were of leaf area to sapwood area ratio rather than HV. I calculated HV from these data, but fixing the problem within TRY may be suitable. I can provide more details if necessary (my email is eavil009@ucr.edu).
Gerhard Boenisch on 2022-06-23 17:16:15Dear Hongge - Read the Data Release Notes supplied
Gerhard Boenisch on 2022-06-23 17:15:05Dear Wangy - Administration -Edit Registration Data
Hongge Ren on 2022-06-22 17:11:55Dear TRY team, Thank you for this amazing resource. I am a relatively new user. I successfully downloaded data for a given set of trait records for all species which I have already defined in the data explorer. I imported the data into R and got a datafram with 28 columns. However, I also need some properties: 1- have leaf type (broadleaved vs. needle-leaved) and leaf phenology type (deciduous vs. evergreen) for tree species and 2- have information about geo-referenced records. Unfortunately I can find none of these information in description of TRY datasets. Do you have any suggestions to help me?
Wangy Yanlin on 2022-06-22 04:47:01Dear TRY team, when registering an account, some information was incorrectly filled in, how can I correct it?
Jens Kattge on 2022-05-12 11:11:38Dear Vanessa, you cannot change your email address or affiliation on the TRY website. To change your email address and affiliation, please email me (jkattge@bgc-jena.mpg.de), and Ill do this for you.
Jens Kattge on 2022-05-12 10:13:28Dear Miriam, Jiefeng and Moria, we had some problems concerning data releases. However, the issues are resolved, and we are getting back on track. You should have received notice about the release of data for your requests. Please accept our apologies for the delay and inconvenience.
Moria Robinson on 2022-05-05 22:31:19Dear TRY team, I am having trouble accessing the data associated with my request (20766; requested 4/25). I received an email on 4/29 stating that "The data for request 20766 have been released". I can navigate to the usual download page via the link in the email. However, when I click the "download" link I am directed to "page does not exist", and if I right click/save target as, a .html file is downloaded, not a linked .zip file. I notice that there is no unique name for the "filename" on the download page. It says "filename: taken". In previous queries to TRY, the download page has shown a unique identifier for the filename, for example "Filename: 20729_22042022204947.zip" Perhaps a file was overwritten? I really appreciate your time. Thank you. Moria
Jiefeng Kang on 2022-05-05 11:16:01Dear TRY team: 1. I have the same problem as Miriam García (post on 2022-05-03 10:54:52), that I havent got the data for my request (Request No: 20760) submitted on April 25th. Is it because of the holiday season and the sickness of the staff (as announced on the main page)? Or did I do it wrong? 2. I wonder if there is any API or R package to download the trait data? I saw a post (Gerhard Boenisch (UserID: 2, registered on 2012-03-22) on 2020-09-14 09:46:23) that mentioned that users can use R to process the data. But I can not find further details about that. 3. Is the forum like an email list under just one topic? Or I can go for details of each post by clicking it or some other operation? I tried clicking the post on Edge and Safari on a mac and nothing happened. Thank you for your time. Kang
Miriam García on 2022-05-03 10:54:52Dear TRY team, I sent out a data request a week ago and have not received a reply so far. I wonder if my operation is wrong or I need to wait. (Request No: 20765)
Vanessa Minden on 2022-03-04 12:04:25Dear TRY team, I changed university and would like that my new email adress is used in the correspondence with potential data-users. But on the webpage I cannot find where to change my affiliation, can anyone help? Thanks!!
Culi Tif on 2022-01-13 23:31:54Dear TRY team, this is an amazing and extremely useful project. Im a botany hobbyist/citizen scientist and also a web developer. I noticed your website got a 49% on a Lighthouse test for accessibility. I think theres a number of ways to increase the accessibility and presentation of the site and I was wondering if youd be interested in working on improving the design together
Zijun Ji on 2022-01-07 08:57:50Dear TRY team, I am curious about the units of each trait, like the Root rooting depth, the data explorer only provide the numer but without units
Zijun Ji on 2022-01-07 08:57:50Dear TRY team, I am curious about the units of each trait, like the Root rooting depth, the data explorer only provide the numer but without units
Maria Kunle on 2021-11-23 17:33:17Dear TRY, my name is Maria, I am working on my MSc thesis related to the functional traits of plants and I would like to use plant height from the TRY database but I am a little bit confused about the methods used for this or that measurements. In particular, there are: - 889 Crown (canopy) base height (ground to base) - 773 Crown (canopy) height (base to top) - 3107 Plant height generative - 3106 Plant height vegetative I am not sure which one I need if I want a height from the ground to the highest point of vegetation (to the very tip of the longest leaf so to say). The traits descriptions are still under construction, is there a place where I can learn how they were measured? And yeah, while I am at it, I would like to really thank you for creating and supporting this amazing database, I find it more than helpful!
Rebecca Hsu on 2021-11-18 10:04:06Dear TRY team, I am very appreciated that youve managed the database so well, and excited to find useful traits of my desire species. And certainly will contribute my data in the future. However, in the registration form, I found my country Taiwan is listed "province of China". I figured it out the problem was from "ISO 3166-1 name". Maybe you can fix it to "ISO 3166-2 codes", then my fellow scientists would be very grateful.
Gerhard Boenisch on 2021-05-25 11:47:08Dear liang ren - Thank you very much for making us aware of this. All temperatures in the file must be multiplied by 10 to be correct. We have updated the file to version 2 with the corrected temperatures. We are really sorry.
liang ren on 2021-05-21 12:13:48Dear TRY team, I may need your help. I am having problems with the attached site data( TRY File Archive ID:24), the maximum value for Mean Annual Temperature across all sites is only 3°C. I would like to know if I have got the units wrong or is there some other misunderstanding?
Gerhard Boenisch on 2021-04-20 11:10:07Dear Eloise - Where are you missing any units? Please be specific, enter DatesetID or URL. There are no missing units in TRY according to my knowledge.
Eloïse SAVINI on 2021-04-20 10:56:24Hello TRY Team, Id like to use your awesome database for my studies, but I cannot without scientific units (g, mm, m², etc), and I dont find how to use standardized units. Will a summary table be uploaded soon ? Thank you and have a good day.
Gerhard Boenisch on 2021-03-10 09:15:44Dear An - are you talking about the Data Explorer or the output for requests? Please indicate!
Gerhard Boenisch on 2021-03-10 09:14:12Dear Megha - You must see the restricted data as an opportunity. If we did not have this feature, these data simply would not be in the database.
An Van den Borre on 2021-01-26 02:29:58Hello TRY team, I have just discovered your site and was very excited about the initiative. However I am having problems finding information about traits. It seems to me that to enable contributors to record data for your system we need to be able to see the trait value options for each trait. Is there any way I can retrieve a list of this? I cannot find how to obtain trait information either. Please add some information. Many thanks and congratulations on a great initiative!
Megha Ojha on 2021-01-12 05:52:05Dear try team, The database is commendable. I feel that though the database claims to be open source, while requesting large set of data, most of the data which needs permission isnt released. That fails the purpose for research groups working with big data and looking up to TRY.
Gerhard Boenisch on 2020-09-21 09:50:40Dear Alex - Sampling dates are included in the TRY ouitput for requests as any other auxiliary data. It is also available from the Data Explorer.
Alex Hurley on 2020-09-21 09:34:30Dear TRY team, thanks for all the work! Is there a way to list/query a time stamp for individual measurements, or infer the temporal coverage of a contributed data set? Many thanks, Alex
Iris Hordijk on 2020-09-18 11:55:29Dear TRY team, Is it possible to publish multiple papers from one TRY data request? Is it also possible that not the first author, but the second author, was the one requesting the data? Thank you for the information!
Gerhard Boenisch on 2020-09-14 09:46:23Dear Anthony - there is only one output per request. You can do this in R on a powerful computer. Alternatively, you can submit more smaller requests.
Gerhard Boenisch on 2020-09-14 09:44:42Dear Lázaro - in the data release notes that are included in the output for each request and is available from About TRY - Administration. Furthermore in About TRY - Database in the section about outliers.
Anthony Benzig on 2020-09-14 08:50:53Dear TRY team, Is there any possibility to cut the txt-data into pieces? After request data for a little bit over 1000 species, I got the data of ALL Species. Now Im not able to work with the data I got. Is there any way to edit the species I want or to split the data into readable pieces? Thank you for your help.
Lázaro Rafael Sánchez-Velásquez on 2020-08-22 21:37:33Dear TRY team, could you help me? Please could you say me were I can see about definition of ErrorRisk? I can not fiand: Thank you.
Gerhard Boenisch on 2020-07-14 10:08:35Dear Juan Pedro - Thios is possible. Simply send us an email and we will take care. Gerhard
Juan Pedro Ferrio on 2020-07-14 09:02:23Dear TRY team, We are planning to upload a dataset that is part of a research article we are submitting (i.e. right now unpublished). Is it possible to update the metadata of a submitted dataset, e.g. to include the final reference once the paper is published? Thanks for your help
Rachel Mason on 2020-06-18 22:49:29Hi Gerhard et al., would you mind supplying some more details about how TRY flags duplicate measurements? Section 4.1.4 of the TRY Data Integration Workflow document gives an overview, but it would also be helpful to know (1) whether the geo-references and dates were truncated or rounded when they were compared, (2) how "similar" two trait values needed to be to be considered possible duplicates (specifically for trait 14, if that matters), and (3) whether "original publication" is synonymous with Primary Reference (DataID 113). I ask because I am merging TRY data with data from other sources and I would like to be consistent with how I identify measurements that might already be in TRY (or at least, properly understand how the TRY team did this). Thanks very much!
Gerhard Boenisch on 2020-05-01 12:39:50Dear Vinay - there are no limits on requests. It is however recommended to submit requests for traits instead of datasets.
Vinay Turpati on 2020-05-01 12:08:55Hi, Im working on a project, I need as much data as possible. Is there any limit to request datasets? If yes, can you tell me whats the threshold?
Gerhard Boenisch on 2020-04-30 18:51:51Dear Vinay - Trait values can only be obtained via a request. So, instead of selecting the measurement table, click the request button, if this is what you want.
Vinay Turpati on 2020-04-30 18:34:24Hello, when I opened "Request by dataset", I chose "Measurement table" but I couldnt find observation values correspond to ObservationId in the table.
Gerhard Boenisch on 2020-03-25 12:02:57Dear Rachel - Sorry for answering late. In the next version of TRY, we will include StdValueStr in the output. This will give you standardized date data. You are right concerning OrigObsDataID and ErrorRisk. The first points to the ObsDataID of the original in case of a duplicate. The second tells you how far the value is from a mean in units of standard deviations. Cheers Gerhard
Rachel Mason on 2020-03-23 17:06:04Hi again, I have been reading the description of the data cleaning carried out on data from TRY 3.0 in Bjorkman et al. (2018), Nature, 562, 7725. The cleaning included identifying duplicates and trait values that were likely to be erroneous. In TRY 5.0, it seems that this is no longer necessary - the OrigObsDataID column identifies likely duplicates, and the ErrorRisk gives a value that can be used to identify possible "problem" measurements. Is that correct? Thanks!
