I have mapped the UUIDs to TCGA barcode using TCGAutils, however, I got some unexplained barcode such as

UUID (Associated Barcode)

3d50d8ca-cabd-4129-80b9-ff1e84c190e5 (CPT0051690007)

54b12749-b94c-4284-a44b-ee890084141b (CPT0069370006)

543965fe-03ea-4cf3-8766-b4c4c8e168ef (HCM-CSHL-0058-C34-85C-01R-A78N-41)

Yes, indeed they are from the "Clinical Proteomic Tumor Analysis Consortium". I downloaded the metadata and it helped me. Thanks Sumit

Yeah sure, dear. It was my first question and thought that it may bring immediate attention. Although latter I resolved this issue myself by downloading the metadata using payload and API. I appreciate your help and guidance. Thank you Sumit

Please avoid terms like "dear". This is a formal, professional setting and these words are of a more personal/intimate nature.

I am pretty sure CPT is from CPTAC, and HCM is from HCMI. Neither are TCGA projects. Btw, using barcode is not a good habit in general. I know there were a few instances of sample type updates in TCGA before. Given sample type is encoded in barcode and some of the file name, this created quite some difficulties for TCGA DCC.
