When I tried to create .den file using Gaussian09 for a molecule containing selenium it showed an error message.

06 June 2017 0 3K Report

I used pop=esp. I was creating the density file for PIXEL energy calculations using Gavezzoti's CLP-PIXEL package. Can anyone tell me how this problem can be solved? It showed the error message "no radius for atom 1 atomic number 34".

I am currently trying to figure out how CLP-PIXEL works.Does anyone know how to create .den file from .gjf file in Gaussian 09?

The step is essential for further PIXEL calculations.
