dear all,
I am simulating four copper nanoparticles places symetrically so that
their centres form a regular tetrahederon.I am trying understand their
sintering behavior.So is their any method to calculate the position of
centre of maas of the whole system at any time (say t) as all the
particles moves causing shift in the centre of maas.!!

Yup... the same way they teach first-year physics students to calculate
the centre of mass. See
http://en.wikipedia.org/wiki/Center_of_mass#Definition
I doubt there's any gromacs analysis tool already written to do this,
however, so you'd have to write a script, or program, or Excel
spreadsheet to do it.
