I am trying to download and prepare expression data with TCGAbiolinks. And I've got several errors.

Code:

query <- TCGAquery(tumor = BRCA, platform = "IlluminaHiSeq_RNASeqV2", level=3)
barcodes <- unlist(strsplit(query$barcode,","))
querySamples <- TCGAquery_MatchedCoupledSampleTypes(barcodes, c("NT","TP"))
TCGAdownload(query, path = "BRCAdata", type = "rsem.genes.results", samples=querySamples)

Error:

Error in fread(paste0(root, url, "/", files[grep("MANIFEST", files)]),  : 
  Expected sep (',') but new line or EOF ends field 1 on line 33 when reading data: -->
In addition: Warning messages:
1: In fread(paste0(root, url, "/", files[grep("MANIFEST", files)]),  :
  Unable to find 5 lines with expected number of columns (+ middle)
2: In fread(paste0(root, url, "/", files[grep("MANIFEST", files)]),  :
  Unable to find 5 lines with expected number of columns (+   last)

I already have downloaded data (3 weeks ago) and TCGAprepare also does not work.

Code:

query <- TCGAquery(tumor = BRCA, platform = "IlluminaHiSeq_RNASeqV2", level=3)
barcodes <- unlist(strsplit(query$barcode,","))
querySamples <- TCGAquery_MatchedCoupledSampleTypes(barcodes, c("NT","TP"))
data <- TCGAprepare(query, dir = "BRCAdata", type = "rsem.genes.results")

Error:

I've read about TCGA portal was down for maintenance. I just want to know if TCGAbiolinks package is to update accordingly TCGA portal.

Thank you!

Hi,

The problem is related to the maintenance of TCGA data portal. 

As we are not sure it will comeback, we are rewriting the code to make TCGAbiolinks use GDC database instead the old TCGA data portal.

There should be an update in the coming weeks in Bioconductor repository.

Best regards,

Tiago
