If you refer to a kind of quiver plots, you could try SPM plus the spm_orthviews plugins available from the SPM extensions page. When you display an image using CheckReg, there will be a context menu (available over each of the displayed sections) which should give you access to "quiver" and "quiver3d" plot options. Feel free to email me off-list if you have any specific questions on that topic. -- 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
