Ramachandran outlier are those aminoacids with non favorable dihedral angles, and Ramachandran plot is a powerful tool for making those evident. Most of the times, Ramachandran outliers are a consequence of mistakes during the data processing. | Ramachandran outlier are those aminoacids with non favorable dihedral angles, and Ramachandran plot is a powerful tool for making those evident.
