[2] Later a number of other papers pointed out additional chemical shift relationships with chi-1 and even omega angles.
[2] PREDITOR was designed to exploit these experimental observations and to help NMR spectroscopists easily predict protein torsion angles from chemical shift assignments.
PREDITOR also supports automated protein chemical shift re-referencing and the prediction of proline cis/trans states.
Several other computer programs including TALOS,[4] TALOS+ [5] and DANGLE [6] have also been developed to predict backbone torsion angles from protein chemical shifts.
These stand-alone programs exhibit similar prediction performance to PREDITOR but are substantially slower.
