Hi Irene, You use menu File / Save PDB... to save coordinates of additional monomers. I'm guessing you are using the Multiscale dialog. In that case you should select the monomer surfaces you are interested in (ctrl click and shift ctrl click to add others to the selection), then use Multiscale dialog "Style Show... / Wire". This will make copies of the monomer for those subunits. You can see the model numbers of those copies in Model Panel (Favorites / Model Panel) and you can save them with File / Save PDB....

I'm working with a pdb structure that's icosahedral. The surface is tiled with hexamers and pentamers of its single chain. The unit cell contains 4 chains, 3 from a hexamer and 1 from a pentamer. I need to compare the pentamer inter-chain contacts to those in the hexamer, so I immediately thought of Chimera.

I can generate a pretty picture of hexamers & pentamers on screen, but what I can't seem to figure out how to do is to save additional coordinates for the other units of the pentamer, analogous to saving additional coordinates when you fill out a unit cell using the "Higher-order Structure" utilities.

Thanks for your help!
