Solvent distribution

Dear all,

Could you please tell me by which command the distribution of solvent molecules (%) around protein based on distance can be calculated?
Solvent (%) per distance from protein (nm).

Many thanks for your response.

Computing radial distribution functions and coordination numbers would be more useful here than SASA. The RDF specifically calculates the enrichment of a given species at a range of distances relative to bulk solution.
