angular displacement

Dear lammps users,

For my system, I want to find the rotational diffusion coefficient and linear diffusion coefficient.

From, the lammps documentation, I could get the linear diffusion coef by outputting the msd/chunk command

Can I output angular displacement of each chunk also?

If so, what is the suitable command?

The command omega/chunk is giving angular velcoties.

Any suggestion is highly appreciated

You have asked this about a year ago and have received answers. Nothing has changed since then. Axel.
