calculation of sequence characteristics from 3D structure

[Tilman Neumann]

Hello,

I'm developing an exemplar based protein secondary structure
prediction system. I think that the classification accuracy
will be the better the more information I'll put in.

Therefore I'm looking for any kind of programs that
calculate characteristics for protein sequences, as well
global characteristics like molecular weight as amino acid residue
wise characteristics like alpha-, beta-propensities or
accesible surface...

One example for such a program is DSSP, that defines secondary
structures and accessible surface area for single residues.

If you know something about similar programs that are available,
it would be very kind of you to send me a note about it.

Thank you very much,
