Molecular Dynamics Analysis GLA
by Benjamin Drexler and Fabian Grandke
Contents
Introduction
In this task we analysed the simulated data that have been created within task 8. We used several tools of GROMACS to analyse the data and Pymol to visualize them.
Methods/Materials
Results

How many frames are in the trajectory file and what is the time resolution?
- 2001 frames
- time resolution of 5ps
How long did the simulation run in real time (hours), what was the simulation speed (ns/day) and how many years would the simulation take to reach a second?
- 18h06:37
- 13.252 ns/day
