Wrong presentation of psi of protein backbone

[InvincibleZZH]

in your doc showing psi angle of protein backbone,
https://userguide.mdanalysis.org/1.1.1/examples/analysis/structure/dihedrals.html
you can see that in the picture psi consists of CAi Ci Ni+1 CAi+1
but it is supposed to be N CA C Ni+1

Thanks for raising this, @InvincibleZZH -- you're right, that was a mistake!

[InvincibleZZH]

also omega
it should consist of current amino acid and the next one
but the illustration is saying that it consists of the last one and the current one

Still wrong in https://userguide.mdanalysis.org/stable/examples/analysis/structure/dihedrals.html

• $\omega$ should take the place of the current $\psi$ (Ci-Ni+1)
• $\psi$ should be attached to CAi-Ci
