So at the end the table above will have one extracolumn at the end for each line with the result of the test ! ...

Comment: C: Use ART illumina to create miRNA simulated data
... I would like to create simulated miRNA reads in order to test a pipeline i already tested for 400 miRNA data sets. I found that ART is the most efficient tool to simulate reads and also there is available a new version from skewer team ( https://sourceforge.net/projects/skewer/files/Simulator/ ). In ...
