Subject IDs

Subject IDs are required if subjects are used in the experiment producing the dataset. Each subject and/or pooled subjects must be assigned a unique ID. This unique ID is used to name the data folders for individual subjects.

• Must have prefixes: ‘sub-‘
• Can include only alpha and numeric characters (0-9, A-Z, a-z), and the dash character (-).
• Special characters and empty spaces are not allowed.
• There is no limit to the character number.

Sample IDs

Sample IDs are required if measurements are obtained from samples, e.g., tissue slices, derived from individual or pooled subjects. Sample IDs must be unique within a single dataset. Each sample should also reference a subject from the subject file; a single subject (a research animal/donor) may be linked to multiple biological samples derived from that subject. If the samples are pooled from multiple subjects, the complete provenance must be specified in the subject file. The metadata present in the samples file should also explicitly note whether a sample was collected directly or was derived from another sample.

• Must have prefixes: ‘sam-‘
• Can include only alpha and numeric characters (0-9, A-Z, a-z), and the dash character (-).
• Special characters and empty spaces are not allowed.
• There is no limit to the character number.
