CCL: Overlay structure

 Sent to CCL by: Daniel Roe [daniel.r.roe|]
 If you would like a scriptable way to do this you could use CPPTRAJ,
 part of the freely available AmberTools
 For example, if your X-ray structure is called X-ray.pdb and your
 optimized structure is called Opt.pdb, you could use the following
 commands in CPPTRAJ to perform a best-fit alignment and calculate RMSD
 for all CA atoms:
 parm X-ray.pdb
 reference X-ray.pdb
 trajin Opt.pdb
 rms ToRef reference ]_[CA out rmsd.dat
 trajout Aligned.pdb
 The structure of Opt.pdb aligned on X-ray.pdb will be written to
 Aligned.pdb, and the RMSD will be written to 'rmsd.dat'. You can also
 calculate the per-residue RMSD if desired via the 'perres' keyword.
 Hope this helps,
