[lammps-users] Visualising cna data

Hi all,

I am trying to visualise Common Neighbour Analysis data generated by LAMMPS. Is it possible to do this in VMD? I understand from previous posts in the forum that it is possible to visualise cna data in AtomEye. But,I am having difficulty running AtomEye on my system. Is there any other software package that can visualise cna data?

Warm Regards,
Nandu Gopan

Hi all,

it might be possible. there are a lot of things that one can do with VMD,
with the help of writing some additional scripts. i've never done CNA
before, so can you explain briefly in what format you have the data,
and how you would like to visualize it. then i may be able to give some
hints and suggestions for how VMD could handle it (or not).

cheers,

In a general sense, CNA is just a per-atom value, like velocity or atom
type. You can add it as an extra column to your dump file. So VMD
can viz it like any other per-atom property, e.g. map it to a color.
