Description
The indels present in the anchors often don't make much sense on the linear reference, leading to non-parsimonious alignments that seem to screw up downstream variant calling. This PR extends the suspicous anchor pruning routine to also trim anchors that partially overlap low complexity sequence and contain indels.
