Hi Margaret,
what are you using to align them? If they are from different sites, then they may not be possible to really align, due to differences in shims, read-out directions and bandwidth. Reconning with a single image is certainly doable (we've done hundreds), but is more labor intensive.
cheers, Bruce

Hello, I am trying to reconstruct brains of patients who had one structural scan during each of 2 visits, a month apart. I averaged the two images together, but since they are from different visits, they look very badly lined up. It looks like there is one image and another image overlaid and shifted by a cm or so. These are clearly wrong and will not work but I was wondering if it was OK to run freesurfer with only one of the images, or if there was a way to line these two images up better so they can be combined? Thanks, Margaret
