I used following commands to download -"Data.category- Biospecimen"
bio_query <- GDCquery(project = "TCGA-PRAD", data.category = c("Biospecimen")) GDCdownload(bio_query)
but received following error
Error in GDCdownload(bio_query) : We can only download one data type. Please use data.type argument in GDCquery to filter results.
My aim is to get the biospecimen,
clinical.info="sample" data . How to solve the problem ?
How to get the normal sample data for the TCGA-PRAD ?
