Dear all, I would appreciate any help about this point. I have a ROI created after a group comparison using functional data. I would like to explore the cortical thickness of this ROI to understand if differences in connectivity are linked to volumetric/thickness differences. I followed the instructions found in Freesurfer tutorials ('cortical thickness of a volume-defined ROI'). However, in the point 4 of the procedure I am not able to change the --reshape default. My run is:
mri_surf2surf --s subj001 --trgsubject fsaverage --hemi rh --sval rh.thickness --tval rh.thickness.fsaverage.mgh --reshape-factor 7
but it continues to create (like default) a reshape with 6.
For this reason, I think, the following command: mri_segstats --seg $SUBJECTS_DIR/rh.fsaverage.mask21.mgh --in rh.thickness.fsaverage.mgh --sum segstats-mask21.txt
give:
ERROR: dimension mismatch between input volume and seg input 27307 1 6 seg 23406 1 7
What can I do to solve this problem?
Thank you for your help!
