Does every piece data from GDC(TCGA) has a unique uuid?
I downloaded the data (mRNA, miRNA and clinical information) for a group of people from TCGA, but there is not a single overlap in terms of uuid for any sample of these three data sets.
So, is there the case that every piece of data has its own uuid? even if these data are for the same person?
If so, how should I match the mRNA data to the clinical information?

From GDC data portal use guide: When an entity is created, it is assigned a unique identifier in the form of a version 4 universally unique identifier (UUID). The UUID uniquely identifies the entity in the GDC, and is stored in the entity’s id property.
As for the last question take a look at this: Retrieving data from new data portal of tcga
Thanks. I guess the fact that the barcode retrieving website introduced here is out of service tonight makes it very confusing for me.
