TCGA: How to detect normal and tumor samples in PRAD dataset?

Question

[carolgalah]

I did the downloaded DNA methylation - Illumina Human Methylation 450 dataset (GDC TCGA Prostate Cancer (PRAD)) using https://gdc.xenahubs.net.

I want to methylation analysis correlation with my RNA-seq data, for this, I need to know which are normal and tumor samples. How can I find this information? Which samples are normal x tumor?

You can infer this from the barcode - please take a look: Meaning letters in TCGA sample barcode field

However, if my memory serves me correctly, there are no (i.e. zero) normal samples for PRAD RNA-seq.

There are some (<=50) solid tissue normals. no blood normals.
