You don't need to specify a mask when you run mri-glmfigt-sim. When you
ran mri_glmfit, you already specified the mask and that gets stored in
the glmdir and then read by mri_glmfit-sim. Your mri_glmfit-sim command
line look right (but you don't need the --bg 1 unless you really want to
background the process, but using only one process will not speed it up).
the other thing I want to point out is that (pseudo) weighted-least
squares will not be taken into account by the permutation. I would rerun
mri_glmfit without --wls and then run mri_glmfit-sim

Hi there,
First, I ran "mri_glmfit" using mask including 4 ROIs(file name:
4_ROI.label) as follows: mri_glmfit --glmdir g2v3.wls --y ces.nii.gz
--wis cesvar.nii.gz --fsgd 2group.fsgd --C group.diff.mtx --lable
4_ROI.label --surface fsaverage lh - --fwhm 5 –eres-save.
Second, I'm going to process "mri_glmfit-sim" to perform a
cluster-wise correction for multiple comparisons.
Please let me know how to process "mri_glmfit-sim" using masks (file
name: 4_ROI.label) .
Is it right? “mri_glmfit-sim --glmdir g2v3.wls --perm 1000 3 abs
--2spaces --bg 1”
Thank you,
Gwang-Won
