Re: [AMBER] ERROR: The unperturbed charge of the unit: 0.010000 is not integral

Hello James,

I see that tleap just ignores the charges <0.01 and according to the
net charge 0.001 from the prepi file, it can't be ignored if I input
more than 10-mer.
This prepi file from the Antechamber and this 0.001 charge is the
result of 3 significant figures under the decimal point, I guess.
Do you know how I can adjust the number of significant figures when
antechamber generates charges? Or do you want me to simply adjust the
charge distribution on this prep file?
Thank you.
