I am trying to understand the fields in a TCGA barcode which is separated by decimal points/dots For example
The filename for the pathology report is TCGA-AK-3460.95FC84F5-4FB3-4CE7-ACD0-C7E0D8F03DD7.PDF
I do not understand what the field 95FC84F5 means which is separated by a dot from the patient ID.
The wiki https://docs.gdc.cancer.gov/Encyclopedia/pages/TCGA_Barcode/ does not seem to describe this scenario.
Can anyone guide me towards a tutorial?
Thanks in advance.
