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:
1) 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
