Hi Virginia, To generate BIOMT-described copies, you would just use the same model as the molecule model and the reference model. For example: open 2o1i sym 0 0 This is mentioned on the "sym" man page, but perhaps it is insufficiently prominent: "A secondary use of sym is to generate BIOMT-described copies of a molecule model, where that model is specified as both molmodel and refmodel." <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/sym.html> Best, Elaine ----- Elaine C.

I am trying to display PDB file 2O1I, which is a DNA structure. I would like to generate the biological macromolecule with 2 strands of DNA, but I'm having a hard time figuring out how to do this. The PDB file has BIOMT records in it and I thought I could use the sym command to generate the other strand of DNA. What do I use for the refmol? Is there a tutorial on this topic?
