Due to sequencing errors occuring with a more random\ndistribution than low frequency variants this approach reduces the number of\namplicon products that must be assigned to target regions & assessed for\nvariant calls. AmBiVErT overlaps forward and reverse reads from the same\namplicon and preserves local phasing information. Typical running time for\nfirst use is several hours, which reduces to less than 10 minutes when the\nhash table calculated on a previous run is supplied for analysis of subsequent\nsamples with the same amplicons.\n\noptional arguments:\n -h, --help show this help message and exit\n -f FORWARD, --forward FORWARD\n a fastq format file of forward direction amplicon\n reads.
