The transformation worked fine but now i have trouble viewing the image on FSL view. I want to overlay the transformed statistics image on the subjects high resolution image, but when i do that i get this error message " unable to load incompatible overlay. all overlays must have same dimensions as the base image". I am not sure why this happens. thanks rajani On Tue, Mar 24, 2009 at 8:34 AM, rajani sebastian <[log in to unmask] > wrote: > thanks!!! > > > On Tue, Mar 24, 2009 at 4:00 AM, Mark Jenkinson <[log in to unmask]>wrote: > >> Hi, >> >> If you are using the same highres image in each case then there should >> be no difference between the standard2highres.mat files. >> >> If you want to transform your statistics, then the statistic images are >> the >> input images.
