Hi,

For this type of analysis I would use MDAnalysis (Python):

Hi Jarrett,

Thank you for your reply. However, that command gives phi and psi angles for only one atom (when only one atom is selected). Is there one command we can use to extract all phi and psi angles?

Thanks,
Neena

    Hi Neena,

    Is this command sufficient?

        Hello PyMOL users,

        How to extract all peptide dihedral angles (phi and psi) in PyMOL?

        Many thanks,
