Filtering Data
Once you browse or search the CSSI DCC data sets and reach a selected investigation details, study details, or assay details page, you can continue exploring the data. The ISA-TAB format is hierarchical, with investigation components becoming more granular as you proceed down the hierarchy. The largest organizing entity is the investigation, which holds one or more studies. Each study includes one or more assays. Assays are composed of samples, which in turn are composed of protocols. Data files are often associated with a protocol.
The following image depicts the hierarchy, without the samples and protocols.
The investigation details page shows only the relationship of the investigation to its studies and assays.
If you select only the study or assay icon, however, you can visualize much more of the investigation file's structure, at a more granular level.The Processes and Filters section of the investigation, study, or details page breaks down the entity to its smallest parts.Â
