[gmx-users] g_rdf: normalize by density

[Archana Sonawani-Jagtap]

Hi,

I want to plot g_rdf for peptide and SDS. In many papers I have read "*The
functions were normalized by the number of atoms in the first selection
(peptide atoms) and by a density of 0.01*".

1) I don''t find any option in g_rdf to normalize by density of 0.01.
There is one option -[no]norm*yes* (Normalize for volume and density) but
no option to put the value 0.01.

2) Does normalized by the number of atoms means to use the below option:
-rdf* enum* atom
 RDF type:  atom,  mol_com,  mol_cog,  res_com or  res_cog

Can anyone please explain.
