[gmx-users] molecular composition of the system

[James Starlight]

Dear Gromacs users!


Sometimes I need to calculate exact numbers of different molecules of
my system based on the initial gro file to add this information at the
end of the topol.top file. Its not trivial task for the big
heterogeneous systems ( e.g protein embeded into the membrane solvated
in water and ions ). How I could make such calculations of total
numbers of lipids, solvent and ions from initial gro file in the most
trivial way ( mb with some external software) ?
