**Purpose**

Program to chart the nucleotide distribution per cycle in a SAM or BAM file.

  ALIGNED_READS_ONLY=Boolean    If set to true, calculate the base distribution over aligned reads only.  Default value:
                                false. Possible values: {true, false}

  PF_READS_ONLY=Boolean         If set to true calculate the base distribution over PF reads only.  Default value: false.
                                This option can be set to 'null' to clear the default value. Possible values: {true,
                                false}

  ASSUME_SORTED=Boolean
  AS=Boolean                    If true (default), then the sort order in the header file will be ignored.  Default: True
