Primer trimming

When primer trimming is enabled, the part of the read that overlaps a primer at the expected position (3' or 5') is unaligned. The unaligned ends are visible in the read mapping, but are not used for variant calling.

When trimming for primer sequence, it is possible to discard reads that do not match a primer. For reads to match a primer, there must af primer overlap of the percentage specified in the tool wizard. In addition, reads must not start upstream of a primer, and only one mismatch is allowed between the read and the primer sequence.
