Hi Julian, > I seem to experience the same problem. Did you find why the image resolution was changed? I want to segment a 1x1x1 image and get native tissue images in 1x1x1 but the Dartel imported in 1.5x1.5x1.5 and I would of course like to keep them in my original resolution. Just as a reminder, this is not as "of course" as it may look like. Citing one of my favorite figures (#3 from Ashburner et al., 1997, p348), you can see that overall scaling to MNI space is ~1.42. In other words, the brain is bigger by that factor already when you write it out to normalized space, which again means that the "same resolution" already requires quite a bit of interpolation (or "inventing" :) Cheers, Marko -- ____________________________________________________ PD Dr. med.
