You need to install the diffusion toolbox helper functions, the are in the diffhelp*.tgz available for download at sourceforge as well. They have to go into the SPM2 folder, and not into any toolbox folder. Volkmar BTW: Please use the sourceforge web site tools (support, bug trackers etc.) for questions specific to the diffusion toolbox. This will reduce the number of off-topic postings to the SPM mailing list. > Can anyone help? > Thanks > Pamela > > > > >> Pamela Perschler > Coordinator of Clinical and Research Programs >> Department of Psychiatry >> Center for Cognitive Medicine >> Neuropsychiatric Institute, Rm 827 >> University of Illinois at Chicago >> 912 S Wood St. MC913 >> Chicago IL 60612 >> Phone: 312-355-5652 >> FAX: 312-413-7856 >> e-mail: [log in to unmask] >> http://ccm.psych.uic.edu/index.htm >> <http://ccm.psych.uic.edu/index.htm> >> >> >
