**Purpose**

Computes a number of metrics that are useful for evaluating coverage and performance of whole genome sequencing experiments.

@dataset_collections@

@description@

  MINIMUM_MAPPING_QUALITY=Integer
  MQ=Integer                    Minimum mapping quality for a read to contribute coverage.  Default value: 20.

  MINIMUM_BASE_QUALITY=Integer
  Q=Integer                     Minimum base quality for a base to contribute coverage.  Default value: 20.

  COVERAGE_CAP=Integer
  CAP=Integer                   Treat bases with coverage exceeding this value as if they had coverage at this value.
                                Default value: 250.
