Wanted: program to extract secondary struct from pdb files

[Steven Paul Adams]

I am looking for a program that will take the atomic coordinates of PDB
files and calculate the secondary structure, based on phi and psi angles
of the residues. I have several PDB files that are missing the secondary
structure information, and I need this info for several of my programs. My
mentor told me that there was one such program developed by Kabsch and
Sander (EMBL, Heidelberg). Where can I find it, or any other program?

Thanks in advance.
