All the currently used diffraction image processing programs can tell the crystal orientation from a single diffraction image.

Some programs like d*TREK can calculate new orientations for the crystal if the crystal is mounted on a reasonable goniometer such as the Rigaku Kappa goniostat or the Rigaku quarter-chi goniostat. :)  And the strategy program in d*TREK can use a list of previously collected and/or processed Bragg reflections to make sure that the new strategy fills in the missing parts of reciprocal space.

Subject: [ccp4bb] crystal orientation during data collection

Hi,
I worked on a crystal sensitive to radiation damage, So I need to merge many crystal to obtain complete dataset, Does anyone know such program that can tell crystal orientation after first frame exposure.
Thank you in advance.
