[gmx-users] How to obtain MSD trajectory for only one direction from g_msd ??

[Kiwoong Kim]

Hi,

It seems that the one directional diffusion constants can be obtained by
means of g_msd ...blabla...-type z.

However, my question is that I don't want to obtain the diffusion constants.

Actually, the MSD trajectory file for all 3 dimensional data can be
obtained by conventional g_msd...
Instead, I want to obtain MSD (time)trajectory file (.xvg file) that
contain only one directional, say z, data.

I want to analyze it and regress it by curve fitting from the MSD data.

How can I do this ?

with best regard
