thanks, christian! katja -----Ursprüngliche Nachricht----- Von: Christian F. Beckmann [mailto:[log in to unmask]] Gesendet: Montag, 25.

If so, use flirt to calculate the registration from functional to structural space. Then use InvertXFM to calculate the inverse transformation ((structural to functional) apply this to the ROI mask. There's more detail on how to call these programs in the course material, check http://www.fmrib.ox.ac.uk/fslcourse/lectures/flirt_fugue/index.html If the data already is in the same space (just at different resolution) you can instead use flirt with an identity matrix and use the -applyxfm -init option. cheers christian On 25 Oct 2004, at 18:05, Katja Meriau wrote: > Hi, > > can anybody help me with this, please: > I'd like to plot the betas of a ROI, but mask and filtered-func are in > different dimensions... > > how can i change the resolution of a 1x1x1mm image to 2x2x2? > Many thanks, katja > > > > > > Dipl.
