I'd like to run APBS command with mobile ions (150 mM NaCl).

I tried the following command, but it did not work.

apbs molecule #1 ion true _posion 1,0.15,1.16 _negion -1,0.15,1.67

If I typed just "apbs molecule #1" it works (without mobile ions).

I am wondering my command was perhaps wrong but don't know the right one.

I hope you could help me to solve the problem

Thank you in advance.
