       vcf-annotate - annotate VCF file, add filters or custom annotations


       cat in.vcf | vcf-annotate [OPTIONS] > out.vcf


       About:  Annotates  VCF  file,  adding  filters  or  custom annotations.
       Requires tabix indexed file with annotations.

              Currently annotates  only  the  INFO  column,  but  it  will  be
              extended on demand.


       -a, --annotations <file.gz>
              The     tabix     indexed    file    with    the    annotations:
              CHR	FROM[	TO][	VALUE]+.

       -c, --columns <list>
              The   list   of   columns   in   the   annotation   file,   e.g.
              CHROM,FROM,TO,-,INFO/STR,INFO/GN.   The  dash  in  this  example
              indicates that the third column should be ignored. If TO is  not
              present, it is assumed that TO equals to FROM.

       -d, --description <file|string>
              Header                      annotation,                     e.g.
              membership'.   The  descriptions  can  be  read from a file, one
              annotation per line.

       -f, --filter <list>
              Apply     filters,     list      is      in      the      format

       -h, -?, --help
              This help message.

       +      Apply  all  filters  with default values (can be overridden, see
              the example below).

       -X     Exclude the filter X

       w, SnpGap
              INT                           SNP  within INT bp around a gap to
              be filtered [10]
