Dear Freesurfer experts, I would like to overlay the significance map and gamma.mgh map from cortical thickness GLM on a semi-inflated surface according to one previous post in the mailing list (shown as below) by using the command (shown) under the directory of fsaverage.
https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2009-November/012445.html<https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2009-November/012445.html> mris_inflate -n <steps> lh.white lh.partially_inflated My questions are: 1) Is it right to generate semi-inflated surface under fsaverage file? Or, I need to generate a semi-inflated surface for each subject (n>500) and make an average surface? How? 2) I tried different 'n', the new generated surface while n=5, 10 or 55 didn't look different at all! Is this normal? It did look very different from lh.white though. 3) Why the generated surface can only be open using tksurfer toolbox, but not a similar command like below? tksurfer fsaverage lh inflated -overlay ./directory_path/gamma.mgh Many thanks for your attention and looking forward to your answers.
