TCGA: how to download matched normal and tumor samples from TCGA website.

Question

[morrovvatim60]

Hi all I want to download those samples from TCGA website, which have both gene expression and miRNA expression data from both tumor and normal tissues ( matched normal and tumor samples) . If a case only has the tumor sample, I want to filter it out. But I didn't find any tags or conditions to do that. Could anyone help me? Thanks in advance.
