[gmx-users] Genion error

[felipe vasquez]

Hi,

I have been trying to add ions to my system so as to make it neutral.
However, I always obtain the same result:

Solvent Group size (950) is not multiple of 9.

The command I entered in this step was:

genion -s protein_w.tpr -o protein_solv.gro -conc 0.15 -neutral -pname NA+
-nname CL-

How could I overcome this error? I realized this problem appears to be very
common; however, I could not obtain an answer for my particular issue so
far. Thanks in advance for your help.

Best regards,
