The results are as follows:
Perform 60 steps of smoothing of input data
Using /usr/local/freesurfer/subjects/groupstudy/lh_std_10.mgh as output file
Using /usr/local/freesurfer/subjects/groupstudy/lh_absmean_10.mgh as output file for abs-mean
Using /usr/local/freesurfer/subjects/groupstudy/lh_mean_10.mgh as output file for mean
Using /usr/local/freesurfer/subjects/groupstudy/lh_absstd_10.mgh as output file for std-of-abs-mean
Reading /usr/local/freesurfer/subjects/1001/surf/lh.thickness_diff.mgh...
Smooth input data by 60 steps
Stats over surface (318651 vertices): mean = 0.0888528, std = 0.334772, absmean = 0.23932, absstd = 0.250386
But I did not get the generated mgh file.Is this what is the reason?

主题: Re: [Freesurfer] ?????? Calculated thickness
Hi yujunjie
in general if you want our help you have to give us more information. We
need for example the full command line you ran and the full output of it
(in text, not a screen shot!)
cheers
