you could use "measure fit" on selected atoms of the equivalent
amino acids and then use the transformation matrix on the whole
system. measure fit just needs the same number of atoms in both
selections. if the order of the atoms doesn't match, you can use
the (still) undocumented "order" flag which takes an index list
similar to catdcd as argument.
cheers,
axel.
