A TCGA barcode such as TCGA-A1-A0SB-01A-11R-A144-07 encodes the project, tissue source site, patient, sample type, vial, portion, analyte, plate and centre, and is the key that joins one patient's data files.
The GDC encyclopedia describes the TCGA barcode as the identifier built from a series of metadata values: project, tissue source site, participant, sample (01 primary tumour, 11 normal), vial, portion, analyte (D for DNA, R for RNA), plate and sequencing centre. The first twelve characters identify the patient and are the join key between expression, mutation, methylation and clinical tables; a tumour and its matched normal share them. The GDC now assigns UUIDs as well, and mixing the two is a common join error.
