Hello Faeze, I'm not sure what you mean by combine, but if you mean changing the relative positions, you can do that by freezing one in place and moving the other with the mouse, as described here: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/mouse.html#activedef> If you mean to put them in the same model, you can try the "copy/combine" function in the Model Panel (menu: Favorites… Model Panel) or the "combine" command, for example: combine #0,1 model #2 … that example would copy both models #0 and #1 into a new model, #2. <http://plato.cgl.ucsf.edu/chimera/docs/UsersGuide/modelpanel.html#combine> <http://plato.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/combine.html> You would want to make the relative positions correct before combining them into a single model, however. Also, there isn't really a need to make a single model. You could just write a PDB file of one model that is in the correct position relative to the other, or just save the whole Chimera session. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/savemodel.html> You can search the documentation for topics such as the word "combine" using the Chimera menu: Help… Search Documentation. I hope this helps, Elaine ---------- Elaine C.
