Hi Jorgen,
I'm not aware of a simple solution; you'll have to write a little
procedure for it. You should be able to copy most of the code from
::Molefacture::rotate_bond (in molefacture_geometry.tcl). Just feed in
your atom indices instead of using the dihedatom array, and don't bother
with the stuff at the end that updates the molefacture graphics. The
selections for atoms on the two sides of the dihedral are calculated in
the highlight_bond proc of molefacture_internals.tcl, which uses
::util::bondedsel.
Best,
Peter
