ID-translation: Translate study identifiers from barcode to UUID and vice...

In waldronlab/TCGAmisc: TCGA utility functions for data management

Translate study identifiers from barcode to UUID and vice versa

Description

These functions allow the user to enter a character vector of identifiers and use the GDC API to translate from TCGA barcodes to Universally Unique Identifiers (UUID) and vice versa. These relationships are not one-to-one. Therefore, a data.frame is returned for all inputs. The UUID to TCGA barcode translation only applies to file and case UUIDs. Two-way UUID translation is available from 'file_id' to 'case_id' and vice versa. Please double check any results before using these features for analysis. Case / submitter identifiers are translated by default, see the from_type argument for details. All identifiers are converted to lower case.

Usage

UUIDtoBarcode(id_vector, from_type = c("case_id", "file_id", "aliquot_ids"))

UUIDtoUUID(id_vector, to_type = c("case_id", "file_id"))

barcodeToUUID(barcodes)

filenameToBarcode(filenames, slides = FALSE)

UUIDhistory(id, endpoint = .HISTORY_ENDPOINT)

Arguments

id_vector	character() A vector of UUIDs corresponding to either files or cases (default assumes case_ids)
from_type	character(1) Either case_id or file_id indicating the type of id_vector entered (default "case_id")
to_type	character(1) The desired UUID type to obtain, can either be "case_id" (default) or "file_id"
barcodes	character() A vector of TCGA barcodes
filenames	character() A vector of file names usually obtained from a GenomicDataCommons query
slides	logical(1L) Whether the provided file names correspond to slides typically with an .svs extension. Note The barcodes returned correspond 1:1 with the filename inputs. Always triple check the output against the Genomic Data Commons Data Portal by searching the file name and comparing associated "Entity ID" with the submitter_id given by the function.
id	character(1) A UUID whose history of versions is sought
endpoint	character(1) Generally a constant pertaining to the location of the history api endpoint. This argument rarely needs to change.

Details

Based on the file UUID supplied, the appropriate entity_id (TCGA barcode) is returned. In previous versions of the package, the 'end_point' parameter would require the user to specify what type of barcode needed. This is no longer supported as entity_id returns the appropriate one.

Value

Generally, a data.frame of identifier mappings

UUIDhistory: A data.frame containting a list of associated UUIDs for the given input along with file_change status, data_release versions, etc.
