Those commands look ok. My suspicion goes to the use of --regheader. See whether the registration is ok with
tkregisterfv --mov negative_allsocial_proportion.nii --regheader --s mni152_subject --surfs --reg reg.deleteme.dat

Hi,
I am trying to compare my volume maps (negative_allsocial_proportion.nii) to someone else's (SN_like_cortical_lh.nii.gz) who have it on a surface (mni152_subject). So I used the steps for mri_vol2surf command as follows:
Commands: mri_vol2surf --src negative_allsocial_proportion.nii --regheader mni152_subject --hemi lh --o ./neg_allsocial_lh.nii --projfrac 0.5 Then to view it: tksurfer mni152_subject lh inflated -overlay ./neg_allsocial_lh.nii -overlay SN_like_cortical_lh.nii.gz -fthresh 0.5
Everything ran fine and we didn't get any error but then while viewing the files we could not see our map (neg_allsocail_lh.nii) on the surface. This file seemed to work fine as it is not an empty file when I checked the file size. However, when we view it using tksurfer it does not show up as a highlighted portion on the surface. The SN_like_cortical_lh.nii.gz file shows up just fine.
Could someone please help me figure out what might have gone wrong here.
Thanks so much!
