Thanks for your suggestion. What was that reference?
I should mention that Chimera does not create bonds automatically -
it just takes the bonds and links specified in the input, and makes
those to metal ions into "pseudobonds" (those purple dashed lines).
We were thinking that such a tool should probably look in the
vicinity of the metal for additional ligands regardless of whether
they were explicitly bonded according to the input file. Other
issues include geometric tolerances and how to deal with missing
ligands (potential water sites).
Your suggestion will be added to the list; just be forewarned that
the list is very long!
p.s. happily I'm not the only "answerer" on this list, but you're
right, I do answer many of the general usage questions!
