Dear Volkmar Thanks for your suggestion I wish it was as simple a that. But in check_reg you can only superimpose an image in different alpha blends of e.g. red this is of little use if you want to correlate an angle to a specific color. What I want is so superimpose an image in say colormap(jet) onto a grayscale image. Much like what one gets in the results section when choosing overlays sections, only I dont have a statistic image rather an image of angles from a retinotopic stimulation. I could of course use FSLview but that is almost too easy! Best Torben Torben E.

While this is possible on a slice-wise basis using display_slices, I was wondering how this could be done with spm_orth_views? Can anybody help? Try the context menu that comes with each section of an image displayed with CheckReg. You can activate this context menu also in other orthogonal sections (Display, results overlays etc) by typing spm_orthviews addcontext at the matlab prompt when image is displayed. -- Volkmar Glauche - Department of Neurology E-Mail [log in to unmask] UKE Hamburg Phone 49(0)40-42803-5781 Martinistr. 52 Fax 49(0)40-42803-9955 20246 Hamburg
