Problem with UUIDtoBarcode

Question

[adrian18_07]

I have a problem with conversion UUID to TCGA Barcode. I use UUIDtoBarcode from library(TCGAutils). My code:

UUIDS <- c("c4e6dc9a-0546-4ee3-b5bf-19872dca172e",
    "078b734e-a871-428f-992e-c292ce767b6f",
    "8a4eb4f8-766f-413e-9b3e-ce382fcf19d8")
res <- UUIDtoBarcode(UUIDS, from_type = "case_id")

And I got result:

Command error 'UUIDtoBarcode(UUIDS, from_type = "case_id")':
No barcodes found, only case and file UUIDs are supported.

I used from_type = "case_id" and "file_id", but it wasn't work.

But if I use another UUID, e.g.:

UUIDS <- c("0001801b-54b0-4551-8d7a-d66fb59429bf",
"002c67f2-ff52-4246-9d65-a3f69df6789e",
"003143c8-bbbf-46b9-a96f-f58530f4bb82")

res <- UUIDtoBarcode(UUIDS, from_type = "file_id")

Everything is ok. Thanks for any help.
