TCGA controlled data access

Hi, I would like to download controlled access TCGA BRCA data both from tcga data portal (vcf files) and cghub (bam files). As far as I read, I need to apply for data access request with PHS000178 to dbgap since they give the data access approvals. TCGA have many types of data, how do we apply for a specific type of data ? Is there another data type specific phs number for TCGA data? In fact we already applied but get rejected, and asked to clarify which dataset we are requesting. Should we just write to application that we want breast cancer data ? Any idea how can we have a request specifically for breast cancer data in tcga ? Thanks Suleyman

You need to pay for the samples to get the data

This is not true, TCGA is a public source. I got all the data without paying anything. Only part of it requires controlled access.
