Next generation sequencers have greatly improved our ability to mine polymorphisms and mutations out of entire (or portions of) genomes. The reliability of their outputs, though, showed to be very related to the sequencing chemistry and to deeply affect the quality of the downstream analyses. We focus here on the two-base color code chemistry of AB SOLiD sequencers and propose a comprehensive quality control methodological and software pipeline. We used existing and custom tools to detect and purge short-reads of some common flaws due to sequencing errors and chemical hitches. We apply them to a cohort of SOLiD 4 runs and measure their joint efficacy in terms of the resulting ability to detect the greatest possible number of true variants.
