Looking for RMS distance calculator

[Luca Jovine]

Dear Netters,

I am looking for a program that could calculate a RMS distance matrix
for a set of homologous molecular structures (possibly in PDB format).
It would be even better if such program allowed to pick which parts of
the structures to compare (for example, only P atoms, or all atoms of
a subset of nts, etc. - as you can guess I need it for comparing some
nucleic acid structures), without having to do it by hand by editing
the PDB files.

Does such a program exist, and, if so, how to get it? (I can use Macs
or SGI or HP or Windows/DOS).

Thank you very much in advance,

                                      Luca
