spherical coordinates

Hi dear LAMMPS users
I want to determine EDL layer around a particle, so I need to calculate concentration of other atoms around this particle (which is not fixed in a specify place) in spherical coordinates. I use fix ave/spatial for other cases, but as I know there is not spherical bins to use in this command.
So what is the solution?
Thanks

I don't know what it means to compute concentration in spherical
coords. You can look at the compute coord/atom command. Something
similar could be written to calcalate any quantity that just depends
on an atom's local neighborhood (e.g. within a cutoff).

hmm... wouldn't this simply be a radial distribution function
multiplied by the total concentration?

after all the rdf (or g(r)) is the ratio of the number density
of particles in a spherical shell relative to a central particle
relative to a homogeneous distribution.
