Investigation Data

You can download selected files, the entire data archive, or only the metadata associated with a studyan investigation. All of the data currently in the portal is public.

The data archive is a compressed (.zip) file that combines the assayinvestigation, investigationstudy, and study assay text files, and associated study data files. The study text files contain the metadata. Downloading the data archive means that you do not need to also download the metadata and files for that investigationEach text file contains only metadata, which appear as column names when imported into a spreadsheet. The data files often contain images and can be a large file size.

If you only need the metadata, you can download it as a compressed file (.zip). The metadata includes only the assay, investigation, and study text files, which are the file columns, field definitions, and placeholders that describe the structure of the data collected in this study. They are in Investigation-Study-Assay tab-delimited format (ISA-TAB), which is based on the ISA-TAB specification

While they are also included in the archive if you choose to download that, you can also download selected study files. These study files might be image files, spreadsheets, or any other data associated with the selected study that is not the metadata.
