[Freesurfer] Error with mri_glmfit_sim (dev version f)

Hi List,

I am getting a couple of strange error when running a 3-group F-test.

WARNING: unrecognized mri_glmfit cmd option mri_glmfit.bin WARNING: 251446 NaNs found in volume analysis/Ftest/cache.th20.pos.sig.cluster.mgh...

And as a result, I consistently get huge clusters:

# ClusterNo Max VtxMax Size(mm^2) MNIX MNIY MNIZ CWP CWPLow CWPHi NVtxs WghtVtx Annot 1 inf 0 63247.45 -38.8 -19.0 66.9 0.00010 0.00000 0.00020 98722 inf precentral

However, this doesn't happen when running t-tests on the same data. Still, I think my F-contrast is correct (see below).

Thanks in advance for any advice!

Nicola

PS:

my F-contrast looks like this:

1 -1 0 0 0 0 1 0 -1 0 0 0

and my design matrix looks like this:

0 0 1 1 179 110 0 0 1 1 193 103 0 0 1 1 176 108 0 0 1 1 198 94 0 1 0 1 186 87 0 1 0 1 217 83 .....
