Hi Colm,
I have encountered 2 problems (in the qform). One is very
obvious in that the directions on two of the axes was reversed,
resulting in 0,0,0 being far outside the dataset. If you don't
have this problem, maybe your system is newer and that has been
fixed.
The other problem is that the origins were off by half of a voxel.
We were able to diagnose these by comparing with corresponding
PAR files.
