Thank you very much, Prof Bopp.

I intend to calculate self-diffusion coefficients.

Thanks for the resource too.

 this is not so easy, see e.g.
 http://ul.qucosa.de/fileadmin/data/qucosa/documents/19515/diff_fund_2%282005%296.pdf

 you probably need to first define more carefully what (i.e. which diffusion phenomenon)
 you want to study

Subject: vmd-l: Calculating Diffusion Coefficient Using VMD

Dear VMD users,

I have a system of heterogenous molecules. I have calculated the Centre of mass coordinates for each molecules using LAMMPS and I have an output file.

I intend to calculate the diffusion coefficient between similar molecules in the mixture. How can I do this please?

Thank you.
