Hi Jonathan
sorry for the delay. If you want us to take a look we'll need more than just the hires T1, we'll also need the whole subject directory. Before doing that though, why don't you try using tkregister2 to create a register.dat between the hires volume and the orig.mgz (if there was no motion you can use --regheader to create it automatically from the header info in the two images). Then use mri_surf2surf to map the white and pial surfaces using mri_surf2surf then see if you can create the ribbon from them.
cheers Bruce

Hi Krish, Bruce, et al.
I just wanted to follow up on the messages below.
We have the problem that when we re-run mris_volmask using a high-res volume (after recon-all and then after re-sampling the aseg file), we get anomalous segmentation: it looks like the surfaces are inside out, as you can see by the side by side comparison. The standard resolution ribbon looks good, but the high resolution ribbon looks inverted. We do not understand why and cannot seem to fix it. The new ribbon is properly aligned to the anatomy, but is mostly unlabeled, except right along the tissue boundaries.
