I am looking for the matched cancer samples and normal samples in TCGA. I used to download these data before but now I seem like can't find the normal samples from the TCGA legacy archive.

I looked up the TCGA barcode and the samples all are cancer sample label 01 but didn't have 11 for the normal samples.

How can I download the normal samples from TCGA ?

Thank you very much for your help.

I have just done this. Firstly, I believe you would need have been granted restricted access to the raw data at the very least.

Then, you will need to goto the GDC legacy archive. And with the facet search it is possible to add a biospecimen filter, search for sample id and enter 11 for normal tissue...........
