You can do that in R using the TCGAbiolinks package (with which you can also download the actual gene expression data as follows) and follow the instructions from the Bioconductor webpage. My script would be as follows:



## Download raw counts for indicated sets
## Example of c("TCGA-GBM")
for (id in{
  clin.query <- GDCquery(project = id, data.category = "Clinical")
  json  <- tryCatch(GDCdownload(clin.query), 
                    error = function(e) {GDCdownload(clin.query, method = "client")})
  ## the following types of clinical data can be obtained (just pick whichever you need)
  clinical.drug <- GDCprepare_clinic(clin.query, = "drug")
  clinical.admin <- GDCprepare_clinic(clin.query, = "admin")
  clinical.radiation <- GDCprepare_clinic(clin.query, = "radiation")
  clinical.patient <- GDCprepare_clinic(clin.query, = "patient")
  clinical.stage_event <- GDCprepare_clinic(clin.query, = "stage_event") <- GDCprepare_clinic(clin.query, = "new_tumor_event")
  clinical.followup <- GDCprepare_clinic(clin.query, = "follow_up")
  clinical.index <- GDCquery_clinic(id, type = "clinical")
  clinical.biospecimen <- GDCquery_clinic(id, type = "biospecimen")
  save(WHAT_YOU_NEED, file = file.path(DIRPREFIX, paste0(id, "_clinical.Rdata")), compress = "xz")

Hello Sir, I am trying to run your code in my 32 bit computer. It says, "cannot open". Does this work only for 64 bit computer? And also can you let me know whether I can save the whole clinical data in csv format?
