Dear list, I want to limit my vertex-wise group analysis to a smaller spatial region, then I ran my own Monte-Carlo simulation on fsaverage for the superior temporal gyrus:
mri_mcsim --o lh/superiortemporal --base mc-z --surface /fsaverage lh --nreps 10000 --label superiortemporal After 36 hours, it finished and I pasted the resulting into $FREESURFER_HOME/average/mult-comp-cor/fsaverage, and ran glmfit: mri_glmfit --glmdir glmdir --y lh.thickness.5.mgh --fsgd table.fsgd --C contrast.mtx --surface fsaverage lh --label /$FREESURFER_HOME/subjects/fsaverage/label/lh.superiortemporal.label It seems it ran only on the label, as expected. However I am not able touse this pre-cached simulation in mri_glmfit-sim. I tried: mri_glmfit-sim --glmdir glmdir --sim-sign abs --cache-dir $FREESURFER_HOME/average/mult-comp-cor/fsaverage/lh/superiortemporal --no-sim mc-z.abs.th13 --cache-label /$FREESURFER_HOME/subjects/fsaverage/label/lh.superiortemporal.label ...but I get an error although the csd files are in /average/mult-comp-cor/fsaverage... path : ERROR: cannot find any csd files I tried several combinations of the text specified after --no-sim, but all I got is the error above. I though I should refer to my own simulation using --cache-dir, but it requires the --no-sim flag. Can anyone help me? Best, Pedro Rosa.
