Hi All!
I want to use Implicit solvent to simulate a nucleic acid sequence.
How can I do it?
I use this command:
genion -s ions.tpr -o nucleic_ions.gro -p nucleic.top -pname K+ -nname
CL -neutral -conc 0.1

ions.tpr file is same as umbrella sampling tutorial.

I got this error message:
Fatal error:
Your solvent group size (2898) is not a multiple of 31
what should I do?

Regards,
Amir
