Downloading Investigation Data
After reaching an investigation entity (such as investigation, study, assay, source, protocol, sample, or data file), you can download the full data, selected metadata, or selected data associated with that entity. The full data is always associated with the investigation as a whole.
Also note that if you selected multiple objects to visualize and filter, a download includes all of those objects.
Metadata describes the structure of the data collected in an investigation and translates to the file columns, field definitions, and placeholders that appear in a spreadsheet. It is in Investigation-Study-Assay tab-delimited format (ISA-Tab), which is based on the ISA-Tab specification
