hi, the method that I am using is that 1, make a cubic of FCC at first, 2 define any parameters as you wish if it can run, 3 define a spherical region and identify it as a group. 4, run the simulation only 1 step and only dump out the spherical group you defined before, 5, transfer dump file into data file.

Hope it help.
