# Coordination analysis

This modifier determines the number of nearest neighbors of each particle within a given cutoff radius (the coordination number).

The modifier stores its results, i.e. the number of neighbors each particle haa, in the `Coordination` particle property.

In addition to determining the number of neighbors of particles, the modifier also computes and displays the radial pair distribution function (RDF) up to the given cutoff distance.

## Parameters

Cutoff radius

  The maximum distance between pairs of particles to be considered neighbors.
