[PyMOL] unable to change phi angle of proline

[Osvaldo M. <alo...@gm...>]

Hi everybody,

I can´t change the phi angle of proline using the function below. It works
for all other amino acids. If quiet = 0, it prints the value of the
variable "phi" (i.e. the value that the phi_angle should adopt). The phi
angle of proline is always around ~11.0

def set_phi(res_num, phi):
    if res_num != 0:
        cmd.set_dihedral('resi %s and name C' % (res_num-1), 'resi %s and
name N' % res_num, 'resi %s and name CA' % res_num, 'resi %s and name C' %
res_num, phi, state=1, quiet=1)


Thanks in advance.
