Molecular Dynamcis analysis

Wildtype

First of all, we checked the resulting file with gmxcheck.

• gmxcheck -f ref_md.tpr.xtc

The Simulation tooked 6h33:50 ans the simulation speed was 36.564 ns/day. So, to reach 1 second of simulation, we had to wait around 75061 years. But this is a bit to long for this Project, so we just used the results we got. The potential energy was fluctuating about -9.185e+05 kJ/mol with a range of about 0.15e+04 kJ/mol. These information are given in the different log-files provided by the simulation.

To create the images, we saved each frame in PyMol<ref>The PyMOL Molecular Graphics System, Version 1.2r3pre, Schrödinger, LLC</ref> as an image, which we converted into gif format. Than we were able to use gifsicle to create an animated gif.

Mutation 8a [C282Y]

still waiting to finish // LRZ won't do anything because of LRZ cluster update

Mutation 8b [C282S]

still waiting to finish // LRZ won't do anything because of LRZ cluster update
