Negative values with VCF filter tool

[jennaj]

UPDATED usage help for negative values when using VCFFILTER

@jennaj

For context, please see this two line discussion from the vcffilter tool author: vcffilter core dumped on negative values · Issue #249 · vcflib/vcflib · GitHub

That means the query you want would be one of these for a negative value:

RPBZ < 0 - 5
RPBZ > 0 - 5

An alternative tool is SNPSIFT FILTER
