Hi Hong,
I would recommend that you check out the services at the VIPERdb website http://viperdb.scripps.edu. It looks like the oligomer tool (http://viperdb.scripps.edu/oligomer_multi.php) might be useful for what you want to do. They have many of the virus structures from the PDB already processed for you, or you could upload your own PDB coordinate file.

Which program should I use to generate a complete virus PDB using the NCS? Thank you Hong Hsiang
