Under the coot Show symmetry option - switch it to 'Symmetry by Molecule> Display as CA' - (click on the Symmetry by Molecule menu item to bring up the Symmetry Controller options window).
Unlike the 'Display sphere' option, with 'Display as CA' you can increase the Symmetry Atom Display Radius by a large number and get a nice simple view of the packing even over several cells. (there is also a colour by symmetry option in the Symmetry Controller window) The clicking on a chain to save still works really well for the CA display version of your packing (kudos to Paul Emsley for this tool). all the best Martyn Martyn Symmons Cambridge On Fri, Dec 9, 2016 at 10:12 AM, Smith Lee <[email protected]> wrote: > Dear All, > > There is a pdb, once opended in coot, it was a monomer (space group P 65 2 > 2 ).
