Dear FreeSurfer Experts,
I'm trying to
downsample the thickness info of subjects (with longitudinal data) to
the same number of vertices as fsaverage6, and would like to save this
output as an mgh file for use in Matlab. I was able to downsample a
single subject using the following command:
mri_surf2surf --hemi
lh --srcsubject 'subjID' --srcsurfval thickness --src_type curv
--trgsubject fsaverage6 --trgsurfval 'output name' --trg_type mgh
However,
it won't allow me to enter multiple subject IDs into the same command.
I'm wondering what's the best way to do this, with the aim of getting a
single mgh file that has the thickness data for all subjects. Do I have
to create a separate downsampled mgh file for each subject and then
merge them?
