BamCmpCoverage

Creates the figure of a comparative view of the depths sample vs sample. Memory consideration: the tool alloc an array of bits which size is: (MIN(maxdepth-mindepth,pixel_width_for_one_sample) * count_samples)^2

Usage

This program is now part of the main jvarkit tool. See jvarkit for compiling.

Usage: java -jar dist/jvarkit.jar bamcmpcoverage  [options] Files

Usage: bamcmpcoverage [options] Files
  Options:
    -b, --bed
      restrict to region
    --filter
      A JEXL Expression that will be used to filter out some sam-records (see 
      https://software.broadinstitute.org/gatk/documentation/article.php?id=1255). 
      An expression should return a boolean value (true=exclude, false=keep 
      the read). An empty expression keeps everything. The variable 'record' 
      is the current observed read, an instance of SAMRecord (https://samtools.github.io/htsjdk/javadoc/htsjdk/htsjdk/samtools/SAMRecord.html).
      Default: record.getMappingQuality()<1 || record.getDuplicateReadFlag() || record.getReadFailsVendorQualityCheckFlag() || record.isSecondaryOrSupplementary()
    --groupby
      Group Reads by. Data partitioning using the SAM Read Group (see 
      https://gatkforums.broadinstitute.org/gatk/discussion/6472/ ) . It can 
      be any combination of sample, library....
      Default: sample
      Possible Values: [readgroup, sample, library, platform, center, sample_by_platform, sample_by_center, sample_by_platform_by_center, any]
    -h, --help
      print help and exit
    --helpFormat
      What kind of help. One of [usage,markdown,xml].
    -M, --maxDepth
      max depth
      Default: 1000
    -m, --minDepth
      min depth
      Default: 0
    -o, --output
      Output file. Optional . Default: stdout
    -r, --region
      restrict to region
    --version
      print version and exit
    -w, --width
      image width
      Default: 1000
