Error if UUIDs from Copy Number File

[DarioS]

I downloaded the file named HNSC.focal_score_by_genes.txt from Genomic Data Commons and the column headings are some kind of UUID. I tried both options of from_type and got the same error. A minimal example is

UUIDtoBarcode("f8c7d038-1182-42d0-8787-b84b5ca57eaf")
Error in names(rframe) <- c(from_type, APIendpoint) : 
  'names' attribute [2] must be the same length as the vector [0]

I am not sure if this is a TCGA problem or a TCGAutils problem. I also downloaded the MAF for this patient cohort and used readLines to import it into R. I then used grep with option fixed = TRUE to search for each of the UUIDs anywhere in the MAF lines and none of the UUID matched any text in the MAF. In any case, the error message could be nicer-looking and user-informative if there was some kind of tryCatch used to provide a clearer error.

Hi Dario, @DarioS

Thanks for your report.
The UUID entered is an aliquot UUID with a barcode of TCGA-UF-A71A-06A-11D-A390-01.
Currently, only case and file UUIDs are supported.

I will add a more informative error.

Best,
Marcel
