VAAL | Specific polymorphism discovery in bacteria using massively parallel sequencing

A package to use massively parallel DNA sequence data to identify differences between bacterial genomes at high sensitivity and specificity. VAAL is a variant ascertainment algorithm which found ~98% of differences (including large indels) between pairs of strains from three species while calling no false positives. During evaluation of the performance on the callable polymorphisms, VAAL shows high sensitivity in finding nearly all of the possible callable polymorphisms.
