Uploading investigation data to the CSSI DCC Portal allows you to curate, manage, and reuse datasets in a standards-compliant way. The ISA-TAB specification describes this standard and how to structure your investigation data to create an Investigation-Study-Assay tab-delimited (ISA-TAB) archive file. This may involve configuring it using open-source software made for this purpose.
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.
