Hi everybody,
I'm working with a pdb file (http://www.rcsb.org/pdb/files/2vxi.pdb1.gz ) made of two models. I need to merge this two models into one. How can I do that?
Thanks in advance,

Hi Maziar, In general, you can merge models with the "copy/combine" button on the right side of the Model Panel (Favorites... Model Panel) or with the "combine" command. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/modelpanel.html> <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/combine.html> However, I opened 2vxi from the PDB and it is only one model, not two. Maybe you opened it two times by mistake? <http://www.rcsb.org/pdb/explore/explore.do?structureId=2VXI> There are a few cases where structures have so many atoms or chains that the PDB has split them into multiple files (e.g. 3bz1 and 3bz2). If those parts collectively have more than 63 chains it won't work to merge them with Chimera because there are only 63 possible different chain ID symbols. Please send Chimera questions to chimera-users@cgl.ucsf.edu and not to me directly, and if possible use an informative "subject" line - thanks! I hope this helps, Elaine ----- Elaine C.
