 made for this purpose.

An ISA archive is a compressed (.zip) file containing multiple text files and data files. Each tab-delimited text file in an ISA 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 archive 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 archive and save it to a folder. If you need an administrator to delete an investigation version from a folder, click the Contact Us link  contact the Center for Strategic Initiatives (CSSI) Data Coordinating Center (https://cssi-dcc.nci.nih.gov/cssiportal/contactus) or click the Contact Us link at the bottom of the screen.

After publishing a file, you may want to unpublish a version of it to remove that version completely from the CSSI DCC server.

Info
titleAccess Control and Unpublishing

When you unpublish a file, all access restrictions that may have been applied to it are removed from the investigation. If you decide to publish this investigation later, you must reapply any access restrictions you want.

To unpublish an ISA-Tab file

  1. Open a previously published file.
  2. Next to the version you want to unpublish, click Unpublish.
    The status of this version becomes Unpublication becomes Unpublication Request Pending. Once an administrator approves the request, the version returns to its unpublished state.
