Dear PyMol Users!

I wounder to know about possible ways of creation of the peptide structures via PyMol Builder module. In particular I need create a linear structure of my protein ( with fixed phi and psi angles) for futher folding molecular dynamics simulation of that peptide. But in builder module I found only helix and sheet conformations for each aa. residue. How I can specify desired values for both torsion angles ?

Also I'd like to know is there any module for pymol wich could be used for obtaining linear unfolded structure for the defined sequence or folded protein ( in pdb) ?
