[Gate-users] Orientation of mhd file

[Simon Rit]

Thanks for sharing the data with us. I tested on my computer and I have the
expected behavior, i.e.,
- the image is upside down because Y goes from bottom to the top on Gate
and it's the opposite in VV,
- if I set
/gate/patient/placement/setRotationAngle          180 deg
then it is back to its normal position
- same thing if I use the enclosed mhd but it is now upside down in VV
- if I do the last two points together, it's back to the original position.
Is this not what you observe?
Simon
