Project-level Metadata Fields
In the Data tab you can visualize all the information about the data available in the active project.
The default metadata fields available in all projects are:
- QC
- Subject ID
- Session ID
- Age (months/years)
- Tags
These default fields are permanent and so are not modifiable via the Metadata Manager explained in section Project-level Metadata Fields Creation and Modification. Their values, however, may be edited, and this is described in section Project-level Metadata Values Modification.
Additional metadata may be added to a project where both the field and its values may be modified. In this example, the header row of the table shows specific metadata fields that are configured as visible to the users of the active project. In this particular case, these correspond to:
- Visit ID
- CGI-I
- Corticosteroid
- Dose (mg)
File-level Metadata (File Info)
In addition to the metadata fields visible at the project level, metadata is also extracted directly from each uploaded file by the Medical Image Data analysis . This includes each file’s modalities and tags, as well as specific file-level metadata extracted from its DICOM headers (see articles Representative Tags for Uploaded Files and Medical Image Upload Data Tool Results). Visualize this additional file-level metadata by right clicking on a pair Subject ID/Session ID in the Data tab and selecting “Show Files”. This will open the “Files” tab displaying a list of all the data of the selected pair Subject ID/Session ID. By selecting one file and clicking “File Info” the below tab will open with all the metadata extracted by the Medical Image Data analysis from the DICOM headers.
