[phenixbb] how to apply phi/psi helical restraints

I was trying to restrain a relatively mobile region of my structure to 
be helical using Phenix secondary structure restraints. The result is 
very bad. It forces the N-O distance to be about 3A, but the phi/psi 
angles are all ugly. What is the way in Phenix I can apply phi/psi 
restraints just like in the old CNS, which had always worked nicely?

Thank you.
