[modeller_usage] a question on MODELLER usage

Hello,

I deal with a peptide (35 residues long). I know its amino acid sequence and a set of mean values for phi- and psi- dihedrals and the respective confidence interval for each dihedral angle. The data is obtained from the NMR experiments. The aim is to obtain a structure with the main-chain dihedrals lying within the corresponding confidence interval for every residue. Side chains can take any conformation. How can such restraints be described in MODELLER?

Thanks beforehand!
