Hi All,If you pass an 4D image to slicer, does it mean over the temporal dimension before creating the png? I ask because we were looking at two slicer outputs that should have been the same data, where one was in Analyze format (passed in a single volume) and the other a 4D nifti, and the nifti image appeared to have much better contrast to noise. (I know nifti is better, but I didn't think that was one of the virtues!)Can you think of anything else that would account for this?Michael
