But you said your atlas is in fsaverage space, no? That is a surface-defined 
space and you should map it to your subject using surf2surf, then use surf2vol 
to put it in each subject's volume space

Hi Bruce,

Thanks for the reply! I didn't convert surf2surf, but convert surf2vol since my 
data analysis is in volume space, do you think that might be the reason? If so, 
do you have any suggestions? Thank you!

Caroline

Did you use mri_surf2surf to map the data from fsaverage to a surface in the 
subject space first?

Subject: [Freesurfer] question about mapping fsaverage surface atlas to

Dear experts,



I am trying to convert an atlas which is in fsaverage surface space to each 
subject's native volume space. However, the alignment seems off (e.g., in the 
parietal lobe, see attached screenshot). I am not sure where the problem is. 
Here is the code that I used:



tkregister2 --mov ${subj_dir}/${subj_id}/mri/rawavg.mgz --targ 
${subj_dir}/${subj_id}/mri/orig.mgz --reg register.native.dat --noedit 
--regheader



mri_surf2vol --surfval lh.Wang2015.mgz --hemi lh --subject fsaverage 
--fillribbon --reg register.native.dat --template 
${subj_dir}/${subj_id}/mri/001.mgz --o lh.Wang2015.native.nii.gz



Any help would be highly appreciated! Thank you!

Caroline
