DNA-seq and RNA-seq bam from TCGA for a single sample

Question

[subhajit06]

Hello all, I am trying to find DNA-seq bam file and RNA-seq bam file from one sample. I also need vcf file for SNV callset. I am looking for some examples from TCGA data. It would be great if anyone could point out a paper that use dataset of this kind. Thanks for your help, --Subhajit

Genomic data commons: https://gdc.cancer.gov/

But you won't be able to get the bam or germline variant calls unless you have dbGap approval. Regardless all the other level 3 data is available for public download. Also bioconductor has a good package called TCGAbiolinks.

Thanks for your answer. We do have controlled data access. I am using GDC with the token to get level 1/2 data.

I wanna know, if anyone knows about a good data set (a set of samples) with both DNA-seq and RNA-seq bam files and vcf file with snv call.

In GDC you can filter for both DNAseq and RNAseq, download the sample metadata, and match for sample id. Just be careful mixing and matching tissue types, also make sure to assess batch effects.
