Suggested topics

You are more than welcome to suggest topics for future theoretical seminars.

Name of topic | Suggestion by

  1. Structural Determination | Mitchell — Done
  2. How to define Clusters and what can we learn from it on proteins properties? | Itamar — Done
  3. Generating the force field for a heteromolecule | Alpesh — Done
  4. Gromacs 4: What's new - What's broken? Breaking the 2fs time step barrier and clever parallelisation.
  5. GROMOS2017 – New developments (Coming soon(ish)!)
  6. Error in Crystal/NMR Structures and their implications.
  7. Determination of secondary structure elements | David — Done
  8. SETTLE/RATTLE/timestep: methods for the simulation of water, implications in our simulations in a world that thinks the 2-fs timestep is because of the C–H bond vibration frequency.
  9. LINCS/SHAKE/dummy atoms
  10. What can be analyzed from simulations? An introduction to the various structural/dynamic properties that can be calculated
  11. NMA/PCA/ED: what are these methods? how good are they? what for?
  12. Sequence alignment, prediction of secondary structures, homology modelling
  13. Of the history of MD: differences between all these forcefields that we always talk about: GROMOS, CHARMM, OPLS, AMBER, GROMACS, GAFF...
  14. Molecular surfaces, NAccess | David — Done
