Welcome to the New T3/Oat

This is the SANDBOX site for T3/Oat. The Sandbox can be used to test the addition of new data to T3/Oat. Data added to this site will be periodically cleared and reset to match the main production version of T3/Oat. For more information on adding data to the Sandbox and submitting it to the production site, see the submitting data sections below.

T3/Oat is the repository of oat phenotype and genotype data for the Global Oat Genetics Database, a project initiated in January 2014 by the following investigators. For more information see the Oat Global website.

• Gabe Gusmini (PepsiCo), • Joe Lutz (General Mills), • Bruce Roskens (Grain Millers), • Nicholas Tinker (AAFC), • Kay Simmons, Jack Okamuro, Jose Costa, Jean-Luc Jannink, and Gerard Lazo (USDA-ARS)

  Leave Feedback

The New T3/Oat is the next evolution of The Triticeae Toolbox (T3). We are in the process of transitioning all of T3's data and tools to this new system. We encourage you to leave feedback about feature improvements, missing tools, and/or any ideas you may have to improve the site.

Submit Phenotype Data

To submit phenotype data to T3/Oat follow these three general steps:

Step 1: Create Upload Templates

Data submitted to T3/Oat should be in the format of the upload template for the data type you are submitting. View the detailed upload instructions for specific information on each data type.

Step 2: Add Data to Sandbox

Once you have your upload templates, you can test-load them on this Sandbox site to check for any errors.

Step 3: Submit Trial Data

If your trial data has been successfully added to the Sandbox you can submit your trials directly to the production site by clicking the Submit Trial button on the trial detail page.

If your data has not been added to the Sandbox or if you would prefer to submit your files directly to the production site, you can submit your individual upload templates or data files to us using the Phenotype Submission Form.
