Hi Fatima,
Sorry for getting in this thread this late, I think there is an
extension in VMD that helps you in building a surface, i think it is
called inorganic builder. Had i known about this i would not have had to
use material studio to build my SiO2 structure.
I don't use pdb for my system (DNA on SiO2) as pdb does not contain
connectivity information, i use mol2 files.
i hope this helps,
Taufik
