Re: [ccp4bb] Rotation angle and translation distance

LSQKAB gives something of what you want.. If you fit domain_open to domain_closed after the rest of the structure is aligned. you get the COM of the two domains. the rotation angles in euler and polar form I would say the rotation angle was the omega angle and the translation the difference b

Well - some things to consider. 1) Rfree will often go up a bit but this seems too much. 2) Does the mz file have the right spacegroup in the header? It is possible to have processed data in one spacegroup and have the Se solution in the enantiomorph.. You might have to actually CHANGE the spa
