Hi all,

I am doing some simulations in binary solvent water and DMSO using ffG43a6
forcefield. I need to calculate the composition fluctuation of the solvent.
I have done that with hand-written codes using the trajectory files
generated by GROMACS. I selected a sphere at a fixed center and noted the
number of water and DMSO molecules within that cut-off. I would like to know
if there are any methods to do the same within GROMACS.

Thanking you,

Saikat
