   Info
   title Versioning ISA TAB Files
   The first time you upload an ISA TAB file to a new project, it is the first version of that file. While it It is a best practice to associate only one investigation with a project, you can make changes to your investigation data, create a new ISA TAB file that reflects those changes, and then upload the new file to the original project. You can upload multiple versions of an ISA-TAB file to that project. You may want to do this if you change your investigation data or need to fix it due to an upload error. Each time you upload a new ISA TAB file to a project, the version number increases by one.

    You are now ready to publish the ISA-TAB file to CSSI DCC.

...

1. Upload at least one ISA-TAB file to a project. 
2. If you have uploaded multiple versions of the file to the project, decide which version of the ISA-TAB file you want to publish to CSSI DCC.  

3. Click the Preview button next to that version.
   The Publish Preview page appears.
   

4. Review the uploaded file by exploring the investigation details. If you are satisfied with the content of this version, request its publication by clicking Publish this Version. If you are not satisfied or the upload generated an error, click Return to go back to your project and upload a new version of the ISA-TAB file.
