Thanks, Doug! I made that rectangle mark on the forehead actually. According to your suggestion, I tried tkmedit test orig.mgz -overlay test_mark.img -overlay-reg reg.dat The only mark that I could find is on the left side of the image in coronal view and nothing in sagittal view. So there is s

In step 3, was the registration correct? You can also try: tkmedit test orig.mgz -overlay test_mark.img -overlay-reg reg.dat the mark should be in the right place. [EMAIL PROTECTED] wrote: Hi all, I got some problems when I tried to overlay some maps one brain surface. The following ste

Hmm, that was not too helpful. Can you do the following: 1. Run mri_info on /space/dilks/filling-in/data/filling-in001/bold/localizer_sm5/avb/sig.bhdr and verify the voxel dimensions. If that is not correct, look at the h-offset.bhdr and h.bhdr volumes in localizer_sm5. If that is not correct
