Distinguishing heterozygous sites from systematic errors

SysCall is a logistic regression based classifier.
Given a list of candidate heterozygous genomic locations and a sam file of sequenced reads SysCall classifies each genomic location as either a heterozygous site or a systematic error and outputs according lists, along with the assigned posterior probabilities.

The slides from a talk on SysCall given at the 2011 CSHL Meeting on The Biology of Genomes can be found here.

The SysCall manual is available here.
