Hi Liang,
I don't understand your geometry well enough to know if kohzuSeqCtl will work. For geometry 2, kohzuSeqCtl expects a Z motion, so the beam doesn't walk off the crystal face as theta decreases. If you don't have a Z motion, you might be able to run in "Freeze Z" mode.
kohzuSeqCtl only controls the motors that must change as theta changes. The other motions in the diagram (chi, theta2, x, y, and x2) are not controlled by kohzuSeqCtl. They are controlled by motor records only.
GEOM selects between geometry 1 and geometry 2.
