No. The transformation code is made for comparing two configurations of t=
he=20
same system. You should in fact get an error message when you compare=20
configurations of different systems. How are you doing it?

There is currently no provision for matching atoms in different molecules=
 in=20
MMTK. Matching by name within a residue is rather easy to code in Python=20
though. What you should do is create a new Configuration object and then=20
store the positions of the matching atoms in it. Then do a superposition =
fit.
