An ISA -Tab archive file is a compressed (.zip) file containing multiple text files and data files. Each tab-delimited text file in an ISA -Tab file archive describes the structure, meaning the column headers and row values when considered in spreadsheet format, of the investigation, study, and assay components of the archive. The data files correspond to each assay and are included in the archive in their native format, for example, Microsoft Excel. An ISA -Tab archive file may also contain images and other files.
Only users who have registered for and logged in to the CSSI DCC Portal can upload investigation data. During registration, you must also select the I would like to upload Investigation data checkbox and be approved. For more information, refer to Registering to Use the CSSI DCC PortalUploading investigation data requires a logged-in CSSI DCC user account with permission to upload. For details on requesting permission to upload data, refer to Managing Your Account.
You can upload a single ISA -Tab archive file and save it to a folder. If you need an administrator to delete an investigation version from a folder, click the Contact Us link at the bottom of the screen.
