$ python -m MrBam.main --help
usage: main.py [-h] [-c CFDNA] [-g GDNA] [-o OUTPUT] [-i INFO] [-q QUAL] [-s]
               [-f] [-v] query

example:
  $ MrBam sample.vcf --cfdna sample_cfdna.bam -o sample_MrBam.vcf --simple

positional arguments:
  query                vcf file contains mutations to query

optional arguments:
  -h, --help            show this help message and exit
  -c, --cfdna CFDNA     bam file contains cfdna reads info. There must be a
                        corresponding .bai file in the same directory
  -g, --gdna GDNA       bam file contains gdna reads info. There must be a
                        corresponding .bai file in the same directory
  -o, --output OUTPUT   output vcf file. Will be overwritten if already exists
  --skip SKIP           skip the first N lines
  -q, --qual QUAL       drop bases whose qulity is less than this (default:
                        25)
  -s, --simple          annotate less infomations into vcf output
  -f, --fast            do not infer origin read size by CIGAR, it can be
                        faster and consume less memory.
  --drop-inconsist      drop different reads stack at the same position. This
                        decreases sensitivity.
  --dropXA              drop reads that has XA tag (multiple alignment)
  -m, --mismatch-limit MISMATCH_LIMIT
                        if set, drop reads that has more mismatches than the
                        limit. requires a 'MD' or a 'NM' tag to be present.
  -v, --verbos          output debug info
