Scientific Questions

Scientific Questions

  • What’s the optimal way of doing torsion fitting?

    • When to run multidimensional scans?

    • When torsions need to be split using chemical perception?

    • How to select which torsions to scan? Avoid scanning linear fragments and standardize selection method 

    • Getting phases right

    • Can optimization datasets minimization energy and gradient histories be used as a cheaper alternative to torsion scans?

  • Is the current LJ and 1-4 scaling optimal?

    • Diagnostics for pathological cases / sterics / 1-4 interactions & electrostatics in torsion drive

    • 1-4 interactions turned on or off?

    • Optimal LJ mixing rules?

  • Do we need specific protein backbone torsions? What data?
