Dear gromacs users, I want to use TraPPE-EH force field parameters in GROMACS-2018.3. I have understood that in top file nbfunc=1, comb-rule=2,fudgeLJ=0.5,fudgeQQ=0.8333. But what will be the values of gen-pairs, nrexcl and [ pairs] section ? Any kind of help will be highly appreciated. Thanks and regards Dhrubajyoti Maji
