you can use moleman2 to generate intermediates between your three xtal structures and morph them. Check out the manual on the USF pages, it's very straightforward. Or you can use the Morph server http://www.molmovdb.org/molmovdb/morph/ Jürgen On Mar 21, 2012, at 10:52 AM, sonali dhindwal wrote: Dear All, My query is slightly out of scope of ccp4. I need some suggestions for making movie using pymol to show conformation of a reactive site loop, through the use of three crystal structure which are available showing this change. I have seen many people present the structural information in the form of movie, to show how the ligands come and the flexible residues moves giving change in the active site by movement of the flexible loops. I found emovie and installed the plugin but pymol installed on my system doesnt support the morph feature. Can someone please help in suggesting some other tool and tutorial for the same. Thanks in advance. Regards ......................
