[Chimera-users] Protein secondary structure

I realize that this is probably simple, but I haven't been able to work this problem out. Is there a way to read a single pdb file into Chimera and then have the program show me what amino acid sequences of the protein are alpha helices, what are beta sheets, and what are 3,10 helices, etc?
