	There is a program developed at the Centre for Structural Biology,
Yale University, called DEFINE_Structure which will do secondary structures
based on c-alpha coordinates. See F.M. Richards and C.E. Kundrot Proteins
3:71-84 (1988) Identification of Structural Motifs from Protein Coordinate Data:
Secondary Structure and First-Level  Supersecondary Structure. You will need
to contact the authors and get permission to download the program from Yale;
I believe there is no cost. 

Hope this helps !
