Hi Srishti, your volume maps are in some template space right? (the template you can open them on) This might be some MNI template space, but not necessarily the same the other people have used. You can register these to one another, e.g. with ANTS:
Start ANTS in terminal > ants.sh 3 TheirTemplate.nii YourTemplate.nii This will give you a transformation matrix (xxx_Warp.nii and xxx_Affine.txt) that you can use to warp your ROIs to their template space: > WarpImageMultiTransform 3 YourROI.nii output_image -R TheirTemplate.nii > xxx_Warp.nii.gz xxx_Affine.txt Then you can open the output image (Your ROI warped to their template space) and their ROI on their template with fslview, or compute any analysis to compare them. I don't understand why you would use mri_vol2surf if you only want the volume. What this function does is to map the volume to the surface, so if you don't need the surface you don't need the fct.

With respect to your third point, comparing volume maps, what exactly do you mean by registering our template to their MNI152 template? What exactly will be our template file? I was using the same mri_Vol2surf for comparing the volume maps as well, for example: mri_vol2surf --src negative_allsocial.nii --mni152reg --hemi lh --o ./neg_allsocial.nii --projfrac 0.5 Best, Srishti Social/Clinical Research Specialist Child Imaging Research and Life Experiences Lab University of North Carolina at Chapel Hill email (W): srish...@email.unc.edu skype: srishti.goel12 On Mon, Mar 19, 2018 at 6:14 AM, Charlotte Grosse Wiesmann < wiesm...@cbs.mpg.de> wrote: > Hi Shrishti, > > 1) by recon-all I meant recon-all in the freesurfer pipeline ( > https://surfer.nmr.mgh.harvard.edu/fswiki/recon-all ) to reconstruct the > subject's cortical surfaces because if I got you right you have the maps on > the surface (SN_like_cortical_lh.gz) and in the volume.
