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!

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
