Finds a specific mutation in a list of VCF files

Usage

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

Usage: findavariation [options] Files
  Options:
    --bcf
      Enable BCF. On 20200217 the java library htsjdk doesn't support the 
      recent version of bcf. This tool will call `bcftools` to get the 
      variants. bcftools must be in the ${PATH}.
      Default: false
    -h, --help
      print help and exit
    --helpFormat
      What kind of help. One of [usage,markdown,xml].
    -homref, --homref
      Hide HOM_REF genotypes
      Default: false
    -indexed, --indexed
      [20171020] Search only in indexed vcf
      Default: false
    -nocall, --nocall
      Hide NO_CALL genotypes
      Default: false
    -o, --out
      Output file. Optional . Default: stdout
    -f, --posfile
      Add this file containing chrom:position
      Default: []
    -p, --position
      A list of 'chrom/position'
      Default: []
    -snp, --snp
      Search only variant have the very same position (ignore overlapping 
      variants)
