This tool allows multiple BAM files to be provided as input and utilizes read group information to make calls for individual samples. + +User configurable options allow filtering reads that do not pass mapping or base quality thresholds and minimum per base read depth; user's can also specify the ploidy and whether to consider each strand separately. + +In addition to calling alternate alleles based upon simple ratios of nucleotides at a position, per base nucleotide counts are also provided. A custom tag, NC, is used within the Genotype fields. The NC field is a comma-separated listing of nucleotide counts in the form of <nucleotide>=<count>, where a plus or minus character is prepended to indicate strand, if the strandedness option was specified. + + +------ + +**Inputs** + +Accepts one or more BAM input files and a reference genome from the built-in list or from a FASTA file in your history. + + +**Outputs** + +The output is in VCF format. + +Example VCF output line, without reporting by strand: + ``chrM 16029 .
