[gmx-users] Issue with Atom Types/Charges/Mass when including ATP in gromos53.a6

Dear all, I want to run some simulations of a kinase with an ATP molecule using gromacs 4.5.1 with the gromos53a6.ff forcefield. To generate the .gro and .top files I am running pdb2gmx -v -f ATP.pdb -p initial.top -o initial.gro -ff gromos53a6 -water spc Now the generated topology file shows so
