Dear Freesurfer experts,
I am very interested in using your permutation approach in order to correct our uncorr analyses using the newly proposed approach (https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MultipleComparisonsV6.0...).
However, I am facing some problems that I hope you can assist me on.
We are computing the uncorrected stats using the mri_glmfit option --frame-mask. However, when I run the (latest) version of mri_glmfit-sim, as in the tutorial, I get the errors:
"""
INFO: unrecognized mri_glmfit cmd option --frame-mask ... probably not a problem
INFO: unrecognized mri_glmfit cmd option ../rh.framemask.mgh ... probably not a problem """
My concern is, since the command is not considering the frame-mask option, it will not also permutate the mask accordingly to the GLM design permutation. Am I wrong or the sim command will permute the mask without problem?
I have also tried to run the mri_glmfit with the --sim option. In this case, I don't receive any warning/info, thus, I am assuming it takes into account the permutation of the frame-mask, or it does not?
One possible workaround would be to create the cluster-extension csd file by myself, but I would know if there is any solution for this already implemented in Freesurfer.
Thank you in advance for your help!
