Add and edit custom metadata

  • Updated

All files stored in Flywheel have corresponding metadata such as upload timestamp, file version, and file type. Metadata has many useful applications in Flywheel including being used to properly categorize data, create collections, or curate a data view. Custom metadata gives you more control over the metadata associate with a project, subject, session, or acquisition. Custom metadata is indexed and searchable just like any of the default metadata fields. Note the one exception to this are files with a leading underscore (for example _myfile.txt); these are not indexed. 

This article describes how to add custom metadata to an acquisition, session, subject, or project.
