you need to add --trgsubject fsaverage to your mri_vol2surf command line

Hello,
We are trying to project a volume map onto a surface. Our network based volume map is a .vmp file and our surface is a nifti file. We were able to convert the volume maps from .vmp to nifti. Our volume map is: negative_allsocial_proportion.nii Our surface is: SN_like_cortical_lh.nii The output file is named: neg_allsocial.nii
We are trying to use the following command to now project the volume map on surface and the issues we are facing are:
- We are unsure of what the purpose of the registration file is and
where in the mir_vol2surf command should we specify the surface 2) If it is a matrix for something related to the surface on which we want to project our volume then how should we go about obtaining the registration file appropriate for our comparison.
_Command:_ mri_vol2surf --src negative_allsocial_proportion.nii --src_type analyze --srcreg [REGISTRATION MATRIX] --hemi lh --o ./neg_allsocial.nii --projfrac 0.5
_Then to project it:_ tksurfer fsaverage lh inflated -ov neg_allsocail.nii
