Dear all
I want to calculate coordination number of water around N+ group. I first calculated area of RDF to first minimum and it gave me a wrong coordination number( my RDF is correct) . Then I used this command gmx rdf -f file.xtc -s file.tpr -b -e -cn coord.xvg -n index.ndx -ref “group N” -sel “group OW”
But, the out put was not coordination number of water around N+( as photo uploaded here)
What is the correct way to calculate coordination number?
Thanks in advance
