Hemochromatosis>>Task 10: Molecular dynamics simulations analysis


Short task description

Detailed description: Molecular dynamics simulations analysis


Protocol

A protocol with a description of the data acquisition and other scripts used for this task is available here.

Calculation statistics

<figtable id="tab:simulation_stats"> Statistics of the MD simulations

Input Calc. time Calc. speed time to reach 1 s
Wildtype 13h31:15 17.750 ns/day 154350,8 years
C282S 13h35:05 17.667 ns/day 155075,9 years
R224W 13h35:02 17.668 ns/day 155067,1 years

</figtable>

GMXcheck revealed for all calculations that all 2001 frames were calculated, resulting in a 10ns model.
