        iVar uses primer positions supplied in a BED file to soft clip primer
        sequences from an aligned and sorted BAM file. Following this, the reads are
        trimmed based on a quality threshold(Default: 20). To do the quality
        trimming, iVar uses a sliding window approach(Default: 4). The windows
        slides from the 5' end to the 3' end and if at any point the average base
        quality in the window falls below the threshold, the remaining read is soft
        clipped. If after trimming, the length of the read is greater than the
        minimum length specified(Default: 30), the read is written to the new
        trimmed BAM file
