I don't know of a direct way to do this, others may know. However, you might
be able to short circuit the radial distribution function code in ptraj.
This lets you specify both a solute and solvent mask. So you could script
something to write you an input file that calculates an RDF between each
molecule of interest and the rest of the solvent. You could then follow
these over time and look for changes that might be indicative of clustering.
I guess this would work but have never tried it.
Good luck,
Ross
