Example data structure for project TCGA-CESC, including 10 randomly sampled patients and full data scope. This example shows how data is stored and organized under the hood by the TCGADataToolUserInterface[]. Files exported in the .m format from the TCGADataToolUserInterface[] will adhere to this format.

In order to be able to demonstrate the selection of genomic data for different samples we make sure that there are patients who have data relative to multiple aliquots, identified by multiple “TumorSampleBarcode”, resulting from multiple genomic files.
