Dear FS experts
Please can you confirm that the NIFTI q-factor in the NIFTI header has to be
negative (e.g. -1) in order to have correct right and left orientation.
When the NIFTI q-factor is positive in my T1-w. and DTI images, then the
left and the right hemisphere seem to be flipped.
Thanks i
Is it possible to rotate the surface model in tksurfer
with the mouse instead of the rotation buttons on the GUI. (i.e. grab the
surface model
with the mouse and spin it)

Hi Jon
glad to see you are now able to post :>. No, I don't think you can do
this in tksurfer due to its age and slow redraw rate. Freeview can do it
though.
cheers

Hi Juergen, how are you judging whether a volume is flipped or not? The
freesurfer tools should display properly regardless of the qfactor as
long as the qform matrix is correct.

Hi Douglas
Thanks for your answer. Our problem is actually not directly related to FS.
We converted Philips .par/.rec files with two different converters, one of
which was recently updated for a new platform and scanner software release,
and realized that they produce different q-form matrices.
