Qualimap
Contents
Introduction
Inspecting bam files for quality. Comes from same home as Blast2Go, the famous functional annotation system, in CIPF, Valencia, Spain.
Installation
Has a number of dependencies:
- optparse (available from CRAN)
- NOISeq, Repitools, Rsamtools, GenomicFeatures, rtracklayer (available from Bioconductor)
Usage
On its own, the GUI will be launched.
However if you launch
qualimap bamqc -bam <bamfile> -outfile <youpdfname.pdf>
it seems to know it should behave in command-line fashion

However, it may not output a PDF file. That was one experience anyway.
