Hi Monami,
It looks like you two ran the program on different machines with different
kernel versions. I think that could cause the differences in output.

Subject: [Freesurfer] Problem with mri_glmfit
External Email - Use Caution
Dear whom may concern
Hello Freesurfer Developers,
I recently ran the mri_glmfit-sim command to replicate a previous PhD student's
result, and found out that his output and mine are different, although the code
and input is exactly the same.
The previous PhD student ran the code in 2022 April, and I ran it in 2023
October.
This is the exact command I run
mri_glmfit-sim --glmdir data/ses-0${timepoint}/${hem}_MM_${variable}_n31_
fwhm_src5trg5.glmdir/ --perm 1000 $sig abs --perm-resid --cwp 0.05 --2spaces;
According to the log, the difference is in the simulation section,
this is his log (2022.04.log)
Starting simulation sim over 1000 trials
mri_glmfit simulation done 42.124
this is mine (2023.10.log)
Starting simulation sim over 1000 trials
INFO: MRImask() using MRImaskDifferentGeometry()
INFO: MRImask() using MRImaskDifferentGeometry()
INFO: MRImask() using MRImaskDifferentGeometry()
INFO: MRImask() using MRImaskDifferentGeometry()
INFO: MRImask() using MRImaskDifferentGeometry()....
mri_glmfit simulation done 27.9102
I attached log files for each to this email.
I searched for what "INFO: MRImask() using MRImaskDifferentGeometry()" means in
FreeSurferWiki, but I can't find any answer. Could you let me know if there are
any updates about this command recently?
1) FreeSurfer version: freesurfer-Linux-centos4_x86_64-stable-pub-v5.3.0
2) Platform: Linux version 3.10.0-1160.21.1.el7.x86_64
