Hi Doug,

I did surface-based inter-hemispheric comparison.

I used an arbitrary surface data (.mgz) resampled from a volume data (.nii), otherwise I follow the instruction.

I got a good result for mri_glmfit. But when I run mri_glmfit-sim, the following error messeage popped up.

ERROR: cannot find

$FRESURFER_HOME/average/mult-comp-cor/fsaverage_sym/lh/cortex/fwhm00/abs/th20/mc-z.csd

I did not find “fwhm00”anywhere in the downloaded file “mult-comp-cor”, although I found fwhm01-30 directories. Am I missing somethine?

Thank you very much in advance,

Shige
