[gmx-users] g_gyrate -p => Calculate the radii of gyration about the principal axes

[Chih-Ying Lin]

Hi
To Calculate the radii of gyration about the principal axes

I use the command
g_gyrate -p

For lysozyme ,   I got  =>
0.922754     1.22249     1.25603

but in some paper, the authors got
=> 0.660  0.833  0.991

It is a quite difference.

what is the definition of the radii of gyration about the principal axes  ?
i have checked the Gromacs manual but see nothing there.


Thank you

Lin
