Hi,

In the manual (for measure
gofr<http://www.ks.uiuc.edu/Research/vmd/current/ug/node135.html>)
it says that it calculates the RDF "for all pairs of atoms in the two
selections" so I guess it takes all the atoms of the protein.
Morevover, from where can I obtain the in-built tcl script for calculation

The source for the plugin can be found under "<VMD install
dir>\plugins\noarch\tcl\gofrgui1.2"
It's a wrapper around VMD's measure gofr and measure rdf commands. But I'm
not sure if these two commands are implemented using TCL. Most probably they
are not.

Ajasja
