When you select Browse, you can browse and explore investigations by organism, disease, cell type, or assays performed. You do not need to log in to the CSSI DCC Portal to browse investigations and download selected files, the entire data archive, or only the metadata.

While the Search Result page includes summaries of all of the studies meeting your filters or search criteria, additional details are available about each study. Click the study title to view the study's measurement types, experimental factors, study description, protocols, and files.
You can then download the full archive, only the metadata, or selected study files. You can also modify your search.
The data archive is a compressed (.zip) file that combines the assay, investigation, and study 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 investigation.
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.
Your role determines which studies you can view in the CSSI DCC Portal. |
To view study details
Click a study title, for example, "Muscle Satellite Cells: MyoD and p53 genes".
The study details page appears.
Click Expand All to view the investigation's associated protocols and files.
The Protocols section is a table showing Protocol Name, Protocol Type, and Description.
The Files section lists File Name, Size, Type, and Submission Date. Enter any keyword from these column names into the search box to search this list. You can also download selected files.
Clicking Modify Search returns you to the Search Result page where you can change how you filter the current investigations. |
An alternative to filtering by investigation is to narrow down a long list of search results by searching within those results.
