Dear FS experts,

I want to know what is the output (volume or surface) of the following scripts.

(The input is file.nii.gz which is a volumetric )

1. spmregister --s subj --mov file.nii.gz --reg reg.dat --o file_t1.mgh #is the output file (file_t1.mgh) is a volume or a surface 

 

2. mris_preproc --target fsaverage --hemi lh --projfrac 0.5 --iv file1_t1.mgh reg1.dat --iv file2_t1.mgh reg ........ --out lh.mgh #is the output file (lh.mgh) is a volume or a surface

 

where I must feed the output of "mris_preproc"? to "mri_vol2surf or mri_surf2surf

 

Thank you for your help
