The problem is that mri_glmfit-sim is looking for a entry in the table that does not exist. The table only goes up to a smoothness level of 35. LGI data tend to bed very smooth. I would strongly recommend that you use permutation instead. See https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MultipleComparisonsV6.0Perm

External Email - Use Caution
Dear Freesurfer experts,

I'm trying to run a simulation (--> mri_glmfit-sim) with cached LGI data (fwhm10), but get an error due to the estimated fwhm kernel. The folder corresponding to the fwhm value (-->37) does not exist, I guess because it's a pretty unusual value...?

DoSim = 0
UseCache = 1
DoPoll = 0
DoPBSubmit = 0
DoBackground = 0
DiagCluster = 0
gd2mtx = dods
fwhm = 36.855100
ERROR: cannot find /apps/prod/x86_64/freesurfer-6.0.1/average/mult-comp-cor/fsaverage/lh/cortex/fwhm37/abs/th20/mc-z.csd

I've seen mails describing similar issues in the archive and from your explanation I more or less understand that you cannot define this value as it is estimated in the process...? However, I did not see if there is a solution to this problem. What could I do about it now?

I attached the logfiles and would be very grateful for your help,

thanks a lot and stay healthy,

Doro
