Christian, as far as I know, PyMol is only able to draw bonds between atoms within the same object. The easiest way would be to combine the pdb files, probably a good idea to give the symm-mate a different chain or segid and then issue the bond command to draw the bond. HTH Carsten

Is it possible to visualize this bond in pymol? Thansk in advance for your help.
