Dear Pymol users,
I would like to modify a protein pdb file with a "crankshaft" flip, which
is the anti-correlated double change: psi(i-1) += delta and phi(i) -= delta.
Such a change should leave the protein coordinates unchanged effecting only
atoms in residues i-1 and i. However implementation in pymol (see below)
changes the coordinates of _all_ residues from i-1 to the C-terminal. Can
you help me? Can I somehow do the two changes simultanious?...
set_dihedral 21/n, 21/ca, 21/c, 22/n, 148.435 #was 168.4
set_dihedral 21/c, 22/n, 22/ca, 22/c, -83.704 #was -103.7
best regards,
Jakob
