Hi I'll assume you mean that you want to change the direct beam position - in iMosflm it's easy, and the best way for you to proceed is to follow the tutorial on the website - see files on
http://www.mrc-lmb.cam.ac.uk/harry/imosflm/ver721/documentation.html especially http://www.mrc-lmb.cam.ac.uk/harry/imosflm/ver721/documentation/tutorial.html If you want to do it in DIALS, I would recommend looking at the "Correcting poor initial geometry" tutorial - https://dials.github.io/documentation/tutorials/correcting_poor_initial_geometry_tutorial.html I don't know of a sensible way to do it directly in ccp4i or ccp4i2 - perhaps someone here can enlighten both of us.
