 **What it does**

+Genetrack supports ChIP experiments.  The peak caller takes a standard set of data on both the sense and
+antisense strands (ScIdx format) and smooths their relative reads. It then predicts the peaks present in
+the smoothed dataset and uses those peak locations to find the maximal non-overlapping subset.  It then
+selects the highest peak and establishes an exclusion zone, and no other predicted peaks will be reported
+within the exclusion zone.  Finally, it ensures each peak is above a threshold and that two peaks are not
 too close to each other.
