Dear Yanming,

You can't really do what you want. The way to do it is to Extensions -> Copy
Fragment, //A/1-550, which produces a molecule which you then undisplay. You
should then Validate -> Ramachandran plot the new fragment/atom selection. It
will take you to the right place when you click on a block, but you won't be
able to select the atom selection for things like real space refinement.

However, the Ramachandran plot won't update, unless you do something like
replace fragment, or some such.

This should be fixed, I've added this feature to the list. Thank you.

Paul.
