2.2.3 Exclude full gap columns

Remove gap-only columns from blocks. This does not modify coordinates and might be necessary after a Subset filter.

Synopsis:

maf.filter=                                 \
    [...],
    XFullGap(
        species=(species1,species2,etc)),   \
    [...]

Arguments:

species=(species1, species2, etc)

A coma separated, within parentheses, list of species. Any column containing a gap in the specified species will be removed. If other species are present in the block, the corresponding character will be removed, whether it is a gap or not. The coordinates of these species will then be discarded.
