Hi SPMers, There is a brain voyager procedure called 'header-based alignment' that uses PAR/REC or DICOM header information as a means of co- registering a functional and structural image from the same session, which can be useful for partial coverage functionals. Does anyone know of any similar tools or code for SPM? Many Thanks, Michael Michael Treadway, MA Department of Psychology Vanderbilt University 301 Wilson Hall 111 South 21st Avenue Nashville, TN 37203 610.909.2565 [log in to unmask]
