To visualize and select study data

Study Hierarchy
The hierarchy of entities for studies according to the ISA-Tab standard is as follows, from less granular to more granular:
Source > Protocol > Sample
For example, click Source. Metadata for that source appears.
Follow this same procedure if you want to filter on Protocol or Sample instead of Source.
- From the Source Name list, click the arrow to open the list of values. Each value is a Source Name from the study file. The screenshots in this page reflect a study file named s_001.txt.
- Click one or more values in the list to select them. Each value appears immediately below the Source Name box. To clear a selection, click the value again.
- Click Filter Results. The Source Count reduces from the original values in the unfiltered study file to the values selected in this procedure. The screenshots in this page reflect four values in the unfiltered study and then two values in the filtered study.
- At this point, you can choose one of the following options:
- Continue to explore this data set.
- Download the metadata of the three values you selected. For instructions, refer to Downloading Selected Metadata.
- Download the selected data of the three values you selected (which includes the metadata). For instructions, refer to Downloading Selected Data to Your Computer.
- Click Clear Filters to filter a different entity.
