annotate a VCF with other VCFs/BEDs/tabixed files

 Vcfanno allows you to quickly annotate your VCF with any number of INFO
 fields from any number of VCFs or BED files. It uses a simple conf file
 to allow the user to specify the source annotation files and fields and
 how they will be added to the info of the query VCF.
 .
   * For VCF, values are pulled by name from the INFO field with special
     cases of ID and FILTER to pull from those VCF columns.
   * For BED, values are pulled from (1-based) column number.
   * For BAM, depth (count), "mapq" and "seq" are currently supported.
 .
 Vcfanno is written in go and it supports custom user-scripts written in
 Lua. It can annotate more than 8000 variants per second with 34
 annotations from 9 files on a modest laptop and over 30K variants per
 second using 12 processes on a server.
