With the merge of UCL/STIR#1016, the quarter_block rotation has been removed from STIR, after STIR v5.0.0. GATE geometries are rotated by 90 degrees about the z axis. A possible solution to this is to rotate the GATE geometry , i.e.
/gate/cylindricalPET/placement/setRotationAxis 0 0 1
/gate/cylindricalPET/placement/setRotationAngle -90 deg
Alternatively, but less desirable, would be to modify the view offset (degrees) value by 90 degrees in the STIR interfile headers.
Additionally, rotational checks need to be rerun for the scanners becasue the all the block/detector offsets have been removed in STIR. This means the mMR geometry is likely broken, see:
