Dear Bruce, dear Freesurfer users
Thanks a lot for the advice. But when using mri_concate in order to average the volumes, there is the following error: "Error: dimension mismatch" between the lh.volume files of the subjects.
We used following syntax:
[thickness, f] = read_curv('lh.thickness') ; [area, f] = read_curv('lh.area') ; volume = thickness .* area; write_curv('lh.volume', volume, nfaces);
mri_concat --i Subjects_*_Kopie/surf/lh.volume --o average_lh_volume --mean
ERROR: dimension mismatch between Subjects_Control01_Kopie/surf/lh.volume and Subjects_Control02_Kopie/surf/lh.volume
Thanks in advance Best regards Juergen

read_curv will return that also:
[thickness_vector, nfaces] = read_curv('lh.thickness') ;
I'm a bit worried that you have a dimension mismatch. That shouldn't happen.

Dear Freesurfer users
I computed ?.volume files by using several commands sent by Bruce. Instead of using the save_mgh.m command, which not really worked because there was a dimension mismatch later when using mri_concat, we used write_curv.m. I need the number of faces in the surface to write ?h.volume files. Where can I get these numbers? Is it the file called f created in the Matlab current directory after running read_curv multiplying area times thickness, and write_curv?
Thanks in advance Best regards Juergen Haenggi
