Hi, Fabian-
OK, thanks for the attached images-- that does help to clarify it. I think you would want your brains "axialized" better: that is, you want the brain rotated in space so that it appears in the field of view with standard view planes/slices.
My guess is that this dataset might have been acquired obliquely -- which is why I asked for the output of that "3dinfo -obliquity .." command -- but that the obliquity matrix info has been lost in the header -- because the 3dinfo command shows no obliquity present.
Soooo, is this the dataset only converted from DICOMs? Or is there an earlier version of it, which you can check to see if it has obliquity information, using either the same 3dinfo command above, or more explicitly for the whole matrix:
3dWarp -deoblique -disp_obl_xform_only DSET_NAME
?
