Hi, All

i am working in pharmaceuticals in japan.

i am so new to Bioconductor, now i am thinking to download data from TCGA database using TCGAbiolinks.

if i tryed to download from TCGA web site, i can download files, however if i tryed to download via TCGAbiolinks,

especially function "TCGAdownload", i failed to download data.

Thanks in advance.

Have you thought about using a graphical interface instead?

The message "Failed to connect to tcga-data.nci.nih.gov port 443: Timed out" happens when the open-access http directory is not reachable for some reason (server is down for maintenance). 

The code below is working for me:

datQuery <- TCGAquery(tumor = "BRCA",
                      platform = "IlluminaHiSeq_RNASeqV2",
                      samples =  "TCGA-A7-A0CH-11A-32R-A089-07")
TCGAdownload(datQuery,type = "rsem.genes.results",samples = "TCGA-A7-A0CH-11A-32R-A089-07")
data <- TCGAprepare(datQuery,type = "rsem.genes.results",samples = "TCGA-A7-A0CH-11A-32R-A089-07", dir = ".")

i am trying to using tcga biolink with commands gdcquery, gdcdownload, gdcprepare.
