Thanks for the reply but if you see the charge group which include N and H is not an integer
10 opls_238 2 ASN N 3 -0.5 14.0067 ; qtot 0.5 11 opls_241 2 ASN H 3 0.3 1.008 ; qtot 0.8 24 opls_238 3 ASN N 9 -0.5 14.0067 ; qtot 0.5 25 opls_241 3 ASN H 9 0.3 1.008 ; qtot 0.8 so wherever NH charge group is the there the total charge is always fraction. Is is correct to continue with this.
