Hi, 

I am having trouble with two modules of TCGAbiolinks (re-installed yesterday) 

1. GDCdownload

and

2. GDCquery_Maf

 

GDCdownload gives the following error, whenever used

> query <- GDCquery(project = "TARGET-AML",
+                   data.category = "Transcriptome Profiling",
+                   data.type = "Gene Expression Quantification",
+                   workflow.type = "HTSeq - Counts")

> GDCdownload(query)

Downloading as: Fri_Aug_05_11_18_18_2016.tar.gz
Error in gzfile(path.expand(tarfile), "rb") : cannot open the connection
In addition: Warning messages:
1: running command 'curl -o Fri_Aug_05_11_18_18_2016.tar.gz --remote-header-name --request POST 'https://gdc-api.nci.nih.gov/legacy/data' --data @Payload' had status 127 
2: In gzfile(path.expand(tarfile), "rb") :
  cannot open compressed file 'Fri_Aug_05_11_18_18_2016.tar.gz', probable reason 'No such file or directory'
> 

GDCquery_Maf gives an error like an infinite loop, and finally the R crashes. 

Please advice.

Hi, I'm sorry. We are still improving/developping the code and the version that was build in bioconductor had a bug, it should be solved very soon as we have already pushed the fix For the moment, please use the github version. You can installing with the following command devtools::install_github(repo = "BioinformaticsFMRP/TCGAbiolinks")

Hi, I tried the github version, but that also is throwing an error

 

> query <- GDCquery(project = "TARGET-AML",
+                   data.category = "Transcriptome Profiling",
+                   data.type = "Gene Expression Quantification", 
+                   workflow.type = "HTSeq - Counts"
+ )
Error in open.connection(con, "rb") : 
  Server returned nothing (no headers, no data)

Hi, the GDCquery is now working as it should, but GDCdownload  is downloading only a partial file.

Note: I am behind a university proxy, could it be due to this? 

> query <- GDCquery(project = "TCGA-ACC", data.category = "Copy Number Variation",
+                   data.type = "Copy Number Segment",
+                   barcode = c( "TCGA-OR-A5KU-01A-11D-A29H-01", "TCGA-OR-A5JK-01A-11D-A29H-01"))
Parsed with column specification:
cols(
  released = col_character(),
  state = col_character(),
  dbgap_accession_number = col_character(),
  primary_site = col_character(),
  disease_type = col_character(),
  project_id = col_character(),
  name = col_character()
)

Hi,

 

They update GDC to version 2.0 and there was a change in the  API. I fixed it, it should be very soon in the bioconductor. Version 2.0.3 and 2.1.3. 

The GDCquery error happend because their server was down for maintenance.

Please, could you test with the github version for the moment.
