Hello,

I was following the TCGAbiolinks tutorial (https://bioconductor.org/packages/release/bioc/vignettes/TCGAbiolinks/inst/doc/download_prepare.html)

but whenever i run the GDCprepare command, it throws following error,

query <- GDCquery(project = "TCGA-GBM",

                  data.category = "Transcriptome Profiling",

                  data.type = "Gene Expression Quantification", 

                  workflow.type = "HTSeq - FPKM-UQ",

                  barcode = c("TCGA-14-0736-02A-01R-2005-01", "TCGA-06-0211-02A-02R-2005-01"))

GDCdownload(query)

data <- GDCprepare(query)

And I checked the URL  to see if the website is available, then it shows as follows,

1. But if i state the summerizedEXperiment to FALSe then the GDCprepare runs without error, but i want to keep that summerizedExperiment option to set to TRUE.

2. So can anyone please help me solve this issue? any suggestions will be valuable.

Thank you.
