Hey Bruce, Thanks for responding. I would actually prefer nonlinear. I did not mention it, but the aseg data that I have is on a distortion-corrected T1 image, whereas the unprocessed image I want to warp onto is the same scan but not corrected for distortion. The distortions are nonlinear. I was hoping there might be a way to get a warp field to go between the two images without running both images through the recon-all pipeline. Are there any other possible tools?
