I have simulations for different peptides in POPC bilayer.
I want to calculate pair distribution function (pdf) between negatively
charged phosphate residue of POPC and positively charged residues of
peptide. Is there any tool available in gromacs for plotting these values?
The closest you can get with a built-in Gromacs program is a radial distribution
function with g_rdf.
Secondly, how to calculate the center of mass for a bilayer?
