Question: Tumor Purity and miRNA / small RNA pipeline

Dear all,

I would like to ask you for two suggestions:

  1. If got an incredible amount of miRNA-Seq data. Can anybody of you recommend a pipline for quality-control and alignment?

  2. I would like to compute the tumor purity from whole gnome seq tumor (with matching control) data. I know that it is hard to get the tumor purity in silico, but I would like to incorporate this information in an analysis pipline I am developing. I "googled" some tools, but I could not find any reports from users concerning the performance. Does anyone of you have a recommendation?

Thanks and best wishes,

miRNA-seq data from small rna-seq library? If it is true, you can try Bowtie (v1) for alignment (recommended for short reads), for quality control try with fastqc, it works for me.

Yep, it is small rna-seq library. I thought about using RNA-SeQC for the QC step and STAR aligner (with proper parameters). As far as I know, STAR and Bowtie (v1) have quite similar performance, when it comes to short reads, despite the fact that STAR is way faster.
