Hi Enrico, I am not sure I understand the question. You just want to superimpose one structure on another to prepare for morphing? There are several ways to superimpose structures, as discussed here: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/superposition.html> The "match" and "matchmaker" methods described in that page keep one model fixed and move the other on top of it. Then you could use "Actions... Focus" or the "focus" command to center the view, or just move both together with the mouse. I can't think of a single command that would move both models but in opposite directions. You could have two commands, essentially moving one model to the right and the other to the left (command "move" is simple translation), but that would not necessarily superimpose them correctly. I hope this helps, Elaine ----- Elaine C.

Dear all, I'm a new chimera user and I'm asking about morphing. I've two models and I'm able to move one to contacts the other. But what if I need to move both to converge on a specific center? There is some shortcut? Thanks to all
