Dear Huy,
When you report a problem, it is helpful to say what version of  
Chimera you are using.

Probably you are looking at documentation that is newer than your  
version of Chimera.  The roll command in your e-mail works fine in  
recent daily builds (Chimera version 1.4) but not the production  
release (1.3), because the syntax has changed.

You can get a new daily build here:

Instead of going on the Web for Chimera documentation, you could just  
use the documentation included with your Chimera download (use the  
Help menu to access or search it, or the "help" command, for example  
"help roll").   That way you won't get confused by documentation from  
different versions of Chimera.

Here is a list of what changed since the production release:
