[VoxBo] group F-test failure and FDR

[David January]

Does anyone know what would cause a subject's statmap made as part of
a group-level/random effects analysis to read NaN when the scale for
the statmap is set to F (and not, for what it's worth, to t or
beta--which I'm taking to indicate that all of the low-level structure
things like have the covariates in the same order across subjects
(which I checked independently anyway) are ok)?

Also, does anyone know why vbstatmap would give me that same threshold
for an fdr of .05 as for .5?
