.. class:: infomark

**What it does**
        
The Radial Distribution Function (RDF), g(r), also called pair distribution function or pair correlation function, can be used to find how density varies as a function of distance from a reference atom. 

_____


.. class:: infomark

**Input**

       - Trajectory file (DCD).
       - PDB file.
       - Segment IDs, residue IDs and names of two atoms to calculate RDF values.

Note that a MDAnalysis 'segment' is a larger organizational unit, for example one protein or all the solvent molecules or simply the whole system.

Other parameters can also be specified: the number of bins in the RDF histogram, and the start and end points for the calculation (i.e. the values of r between which RDF will be calculated).
_____

        
.. class:: infomark

**Output**

       - Tab-separated file of raw data of the RDF.
       - Image (as png) of the RDF plot.
