I'm relatively new to NGS processing but thanks to this forum (and the excellent documentation provided by the Broad) I was able to put together the following pipeline for this project:

I just wanted to check with the Cancer Team that everything looks OK, as well as get any suggestions, if possible.
Looking forward to your valuable response,
