Web2- I'm looking for the possible way to set the values for psi and phi dihedral-angles. As I understood the commands like torsion or set dihedrals need in the definition of the edited angles. Is there more trivial way to set values for the pre-defined backbone dihedrals like set phi value, sele, 120 ? :) Web18. sep 2024 · The mean absolute error (MAE) of phi and psi angles predicted by DRNN, DReRBM, DRBM and DNN is about 20–21° and 29–30° on an independent dataset. The MAE of phi angle is comparable to the existing methods, but the MAE of psi angle is 29°, 2° lower than the existing methods. lego store meadowhall sheffield
