You can select any groups you want for RDF calculations, around any central 
reference group you like.  You can probably do in vacuo RDF, though you probably 
have to use -nopbc.

Dear all
   I have two discrete residues which are being connected together by sulfur 
atom in each residue. I need to find how the density varies around the residues 
or atoms attached with the sulfur atom and the water molecules surrounding it.  
for that I created a group by selecting the two sulfur atoms using the index 
file. By giving RDF command Can I select the group which I created by index 
file as first group and the system as second group. And also is it possible to 
have RDF for vacuum phase simulation. 
                               Thanks in Advance
