Usage:
bam2msa [flags...] <ref> <bam> <regions> [arg...]
convert bam to msa format for alignment file
Flags:
--colorize-snp-indel (default: 0) # colorize snp and indel of output
--display-read-boundary (default: 1) # display the read boundary, 0 mean not display
--help # Displays help for the current command.
--measure-run-time (default: 0) # measure the run time of code
--primary-only (default: 1) # only for primary alignment. 0 mean all alingment, 1 is only primary alignment
--span-whole-region-read-only (default: 0) # only for read which span the whole region. 0 mean all read which overlap with the region, 1 mean is read which span the whole region
--version # Displays the version of the current application.
Arguments:
ref (required) # ref fasta file
bam (required) # bam alignemnt file or STDIN
regions (required) # display read and ref msa alignment in these regions, example: chr1:1000-1200,chr2:2000-2300
