VcfSetSequenceDictionary

Set the ##contig lines in a VCF header on the fly

Usage

Usage: vcfsetdict [options] Files
  Options:
    -ho, --header-only
      only change the vcf header. Keep the whole VCF body unchanged. The idea 
      is to use a faster(?) `sed sed 's/^chr//' ` for the VCF body.
      Default: false
    -h, --help
      print help and exit
    --helpFormat
      What kind of help. One of [usage,markdown,xml].
    -n, --onNotFound
      Contig converter. I will do my best to convert the contig names (e.g 
      'chr1' -> '1'): But what should I do when comparing two dictionaries 
      with different notations
      Default: SKIP
      Possible Values: [RAISE_EXCEPTION, SKIP, RETURN_ORIGINAL]
    -o, --output
      Output file. Optional . Default: stdout
  * -r, -R, --reference
      Indexed fasta Reference file. This file must be indexed with samtools 
      faidx and with picard CreateSequenceDictionary
    --version
      print version and exit
