Hi Zixuan
didn't I answer this? If you run
mris_inflate -w 1 -scale 1 lh.white lh.white_inflated
it will save snapshots at every iteration and you can pick how inflated you want it.

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....
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.
Best regards,
Zixuan
