Hi Steve,
Chimera doesn't include anything to do this, sorry. I believe you would just need a script to reverse the signs of all x, or all y, or all z atomic coordinates depending on the desired plane of reflection.

How can I invert the configuration of a pdb file to create the mirror image model

Yes, you could write a Python script, or if you are just doing this once, type this into the IDLE interpreter (under General Controls):

m = chimera.openModels.list()[0]

for a in m.atoms:

crd = a.coord()

crd.x = 0 - crd.x

a.setCoord(crd)

The above assumes that the model you want to invert is the only one open, and inverts it in x (i.e. across the yz plane). Changing the script to invert in y or z is obviously trivial.

Hope this helps.
