+## DATABASES #

+## This section enables you to configure multiple genomes databases (aligner index 
+## files) to search against in your screen.  For each genome you need to provide a 
+## database name (which can't contain spaces) and the location of the aligner index 
+## files.
+##
+## The path to the index files SHOULD INCLUDE THE BASENAME of the index, e.g:
+## /data/public/Genomes/Human_Bowtie/GRCh37/Homo_sapiens.GRCh37
+## Thus, the index files (Homo_sapiens.GRCh37.1.bt2, Homo_sapiens.GRCh37.2.bt2, etc.) 
+## are found in a folder named 'GRCh37'.
+##
+## If, for example, the Bowtie, Bowtie2 and BWA indices of a given genome reside in 
+## the SAME FOLDER, a SINLGE path may be provided to ALL the of indices.  The index 
+## used will be the one compatible with the chosen aligner (as specified using the 
+## --aligner flag).  
+##
+## The entries shown below are only suggested examples, you can add as many DATABASE 
+## sections as required, and you can comment out or remove as many of the existing 
+## entries as desired.  We suggest including genomes and sequences that may be sources 
+## of contamination either because they where run on your sequencer previously, or may 
+## have contaminated your sample during the library preparation step.
