You might check to be sure debabler did not swap right and left without telling you, as I had that problem with that software several years ago. Peace, Matt. -----Original Message----- From: FSL - FMRIB's Software Library [mailto:[log in to unmask]] On Behalf Of Michael Lipton Sent: Monday, March 24, 2008 5:26 PM To: [log in to unmask] Subject: [FSL] Philips DTI conversion Just to let anyone interested know that I was able to work around the annoying slice ordering issue with Philips (Achieva 3T r2.5) DTI data. While dcm2nii was not useful because it generated negative pixel values, the LONI Debabeler did a superb job, creating a set of 3D ANALYZE files (one for each direction) that I was then able to combine with fslmerge. Kudos to Scott Neu and colleagues! Michael
