Syntax
The following table describes the keywords and options that can be used with this action
| Keyword | Type | Default | Description |
|---|---|---|---|
| GROUP | input | none | the atoms that are being used to calculate the RDF |
| ATOMS | input | none | the atoms that are being used to calculate the RDF |
| GROUPA | input | none | the atoms that you would like to compute the RDF about |
| GROUPB | input | none | the atoms that you would like to to use when computing the RDF around the atoms that were specified with GROUPA |
| GRID_BIN | compulsory | none | the number of bins to use when computing the RDF |
| KERNEL | compulsory | GAUSSIAN | the type of kernel to use for computing the histograms for the RDF |
| CUTOFF | compulsory | 6.25 | the cutoff at which to stop evaluating the kernel functions is set equal to sqrt(2x)bandwidth in each direction where x is this number |
| MAXR | compulsory | none | the maximum distance to use for the rdf |
| BANDWIDTH | compulsory | none | the bandwidths for kernel density esimtation |
| CLEAR | compulsory | 1 | the frequency with which to clear the estimate of the rdf |
| STRIDE | compulsory | 1 | the frequency with which to compute the rdf and accumulate averages |
| SIGMA | compulsory | use bandwidth | an alternative method for specifying the bandwidth instead of using the BANDWIDTH keyword |
| DENSITY | optional | not used | the reference density to use when normalizing the RDF |
