## Syntax

**DYNAmics****ANALysis RDF { dynamics-rdf-statement } END**is invoked from the main level of X-PLOR.**dynamics-rdf-statement :==**-
**trajectory-statement**- defines the input data; see Section 12.1.3.
**ASPEcies=selection**- selects “A"-species.
**BSPEcies=selection**- selects “B"-species.
**DENSity=real**- adjusts the density to normalize the distribution (default: 1).
**MINImum-image****BOXX=real BOXY=real**defines x,y,z dimensions of a rectangular box for periodic boundary conditions (default: no periodic boundary conditions).

BOXZ=real END**MODE=AVERageCENTerPOINt**- provides alternate ways of computing radial distributions. AVERage computes radial distributions around each A-species atom within RADIus around ORIGin and averages them. CENTer computes the distribution around the geometric center of all A-species. POINt does it around the fixed ORIGin.
**ORIG=vector**- is explained under MODE (default: (0 0 0) ).
**OUTPut=filename**- writes the radial distribution function to the specified file (default: OUTPUT).
**RADIus=real**- is explained under MODE (default: 0).
**RGRID=real**- is the interval between values of for which is evaluated (default: 0.05).
**RMAX=real**- provides the maximum value of for which radial distribution function is calculated (default: 10.0).
