Dear All Does anyone have experience in using APBS to create .grd file? How to specify the parameters in the ELEC part? I use "mg-auto" type and "dime 65x 97y 129z" keywords. The program said: "MGparm_check: CHGM not set! Nosh: MG parameters not set correctly!" But I think "CHGM" is a keyword for "mg-manual" type. Any advice will be appreciated.
