Hi all,

I had a question when convert a surface to volume space.

First, I converted a volume nifti data to fsaverage:

mris_preproc --target fsaverage --hemi lh --iv data.nii bb_register.dat --out data.lh.mgh

Then, I want to convert the data.lh.mgh to volume space, I tried mri_surf2vol, however, it needs register.dat. As I understood, the data.lh.mgh was already registered to fsaverage surface, so how can I get the required register.dat file? Thank you for your attention.

Best, Xiangyu
