1- What exactly is the Sculpping ? As I've understood its something like real-time minimisation of the edited structure. Is what cases this might be better than rigid rotation\edition of the selected bonds/ angles by mouse-mode editing ? :)
It's a geometry optimizer. It has bond/angle/torsion/vdw terms as far as I can judge from the various sculpt_* settings and the "Build > Sculpting" menu.

2- I'm looking for the possible way to set the values for psi and phi dihedral-angles. As I understood the commands like torsion or set dihedrals need in the definition of the edited angles. Is there more trivial way to set values for the pre-defined backbone dihedrals like set phi value, sele, 120
see attachment. It's the function from DynoPlot, modified to work with selections.
Note that you can quickly query phi/psi angles with "phi_psi" command. Cheers, Thomas -- Thomas Holder MPI for Developmental Biology Spemannstr. 35 D-72076 Tübingen
