.. class:: infomark

**Purpose**

Reads a SAM or BAM dataset and writes a file containing metrics about the statistical distribution of insert size (excluding duplicates) and generates a Histogram plot.

  DEVIATIONS=Double             Generate mean, sd and plots by trimming the data down to MEDIAN + 
                                DEVIATIONS*MEDIAN_ABSOLUTE_DEVIATION. This is done because insert size data typically 
                                includes enough anomalous values from chimeras and other artifacts to make the mean and 
                                sd grossly misleading regarding the real distribution.  Default value: 10.0. 

  HISTOGRAM_WIDTH=Integer
  W=Integer                     Explicitly sets the Histogram width, overriding automatic truncation of Histogram tail. 
                                Also, when calculating mean and standard deviation, only bins &lt;= Histogram_WIDTH will be 
                                included.  Default value: not set. 

  MINIMUM_PCT=Float
  M=Float                       When generating the Histogram, discard any data categories (out of FR, TANDEM, RF) that 
                                have fewer than this percentage of overall reads. (Range: 0 to 1).  Default value: 0.05. 

  METRIC_ACCUMULATION_LEVEL=MetricAccumulationLevel
  LEVEL=MetricAccumulationLevel The level(s) at which to accumulate metrics.    Possible values: {ALL_READS, SAMPLE, 
                                LIBRARY, READ_GROUP} This option may be specified 0 or more times. 
 
  ASSUME_SORTED=Boolean
  AS=Boolean                    If true (default), then the sort order in the header file will be ignored.  Default 
                                value: true. This option can be set to 'null' to clear the default value. Possible 
                                values: {true, false}
