[gmx-users] radius of gyration and moment of inertia

[Aishwarya Dhar]

Hi,
I am trying to find the moment of inertia of an aggregate.
I have used the command gmx gyrate -f  test.gro -s test.gro -p yes -mol
yes  -o out.xvg

For two aggregates the the shape is similar but the values are
very different for Ix Iy Iz

For an aggregate 1
Ix                 Iy              Iz
81538.8      243689      251837

For aggregate 2
Ix                   Iy                 Iz
144172      498275      517148
Could you please help me as what could the possible solution?



Thanks in advance
Aishwarya
