[Vcftools-help] What does the disclaimer under "Genotype Filters" on the Options page mean?

[Karen K. <kar...@gs...>]

Under "Genotyping Filters" (options page):

http://vcftools.sourceforge.net/options.html#geno_filter

it says:

The following options are currently inconsistently implemented, and should therefore be used with care.  Could someone please provide further insight?

Does this mean there are known bugs?  Or, don't combine them with other options?  Or, depending upon variations in file format, this may not work?

I am trying to determine if use of this option would be appropriate for a project I am working on that requires genotype-level filtering.

Thanks!
