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 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.

Only users who have registered for and logged in to the CSSI DCC Portal can upload ISA-TAB investigation data.
