Dear Yuri, Do you know "supercell" script for Pymol? http://www.pymolwiki.org/index.php/Supercell It is more convenient than standard [Action]-[Generate]-[Symmetry Mates] command in Pymol.
If you want programs other than Pymol, CueMol can also do it. http://cuemol.sourceforge.jp/en/ If you want to put it on Web pages, you can use Jmol. GLmol, a WebGL/Javascript based viewer I am developing, can also show packing and unit cell if symmetry operations are defined in REMARK record. http://webglmol.sourceforge.jp/index-en.html Takanori Nakane
