Usage: bednonoverlappingset [options] Files
  Options:
    --compress
      Bgzip outut bed files
      Default: false
    -x, --extend

    -R, -r, --reference
      Indexed fasta Reference file. This file must be indexed with samtools 
      faidx and with picard/gatk CreateSequenceDictionary or samtools dict If 
      defined, will be used to sort the bed record on chrom/pos before writing

Motivation

GATK DepthOfCoverage merge overlapping segments (see https://gatkforums.broadinstitute.org/gatk/discussion/1865/ ). I wan’t to get the coverage for a set of overlapping windows.
