[gmx-users] solvent molecules between protein-peptide complex

[Alok]

hello gromax users,
                               I have simulated a protein-peptide 
complex solvated in water.
 Now i want to specifically analyse the number of solvent molecules 
between the protein-peptide complex as a function of time.
Is there any direct or indirect tool available in GROMACS to help me 
carry out this analysis.
Please suggest some solution.
Thanking you all in advance.
                                              Alok Jain.
