 Invokes hgVai (Variant Annotation Integrator) on a set of variant calls to
 add functional effect predictions (e.g. does the variant fall within a
 regulatory region or part of a gene) and other data relevant to function.
 
 input.(...) must be a file or URL containing either variants formatted as VCF
 or pgSnp, or a sequence of dbSNP rs# IDs, optionally compressed by gzip.
 Output is printed to stdout.
 
 options:
   --hgVai=/path/to/hgVai          Path to hgVai executable
                                   (default: $hgVai)
   --position=chrX:N-M             Sequence name, start and end of range to query
                                   (default: genome-wide query)
   --rsId                          Attempt to match dbSNP rs# ID with variant
