        ## trim_galore removes .fastq and .fq file extensions of input files.
        ## This is essential if Galaxy provides links to files (with real extensions)
        ## but that behaviour is causing an inconsitency in output filenaming.
        ## We work around this by linking every file to cwd without file extension

**What it does**

TrimGalore_ is a wrapper script that makes use of the publically available
adapter trimming tool Cutadapt.

.. _TrimGalore: http://www.bioinformatics.babraham.ac.uk/projects/trim_galore/


It is developed by Felix Krueger at the Babraham Institute.
