Dear Pavan,
could you give your specific input and the error you get? Format 3
should work. Note that you can also get your transformations directly
from vmd commands, eg, rotation of 180 degrees about the x axis can be
done by
$sel move [transaxis x 180 deg]
These commands are documented at
http://www.ks.uiuc.edu/Research/vmd/current/ug/node176.html.
Best,
Peter
