>>Recently, I' ve run firefly (PC-Gamess) successfully under parallel mode in my computer. However, when I calculate the chelpg charge of a cluster, it seems that I can't custom the radii of atoms in the cluster. I know the program does the calculation with Breneman, Wiberg radii automatically, and I wonder whether I can define the radii of atoms.
>>I've asked Dr. Granovsky this question, he said I should use "$vdwrad radius(30)=2.3 $end" to set vdw radius of element with atomic number 30 to 2.3 angstrom, but firefly shows the error message in the log file:
