Thanks Robert and Jason
Indeed, I have different small molecules as Robert surmised and subsequent
ones affect the connectivity of the earlier ones (and representations for
some reasons, colors and spheres, etc. become unpredictable) when using the
create command. I had noted that "discrete" flag for the load command, but
not having separate files from these aligned in the right spot is there
really nothing similar to do on the fly without saving out the newly aligned
(using the surrounding protein) and extracted ligand into its own pdb file
and loading that back in again with the discrete flag on? That will work,
but seemed a bit clunky!
Thanks again for the tips to that functional route!
Cheers,
Seth

It sounds like you are loading a set of *different* structures into the
multi-state object. I don't think you can do this properly with the
"create" command. I think the only way to do this and retain the correct
bonding information is to use the load command directly with the
"discrete=1"
option.
So, you need to do:
load this_ligand, all_lig, discrete=1
load next_ligand, all_lig, discrete=1
Cheers,
Rob
