[Chimera-users] volume of an ensemble

Dear Chimera Team, Is it possible to get the total volume that encompasses an ensemble of structures? For example, if a docking or structure calculation produces an ensemble of structures, can one calculate the volume that encompasses all the members of the ensemble? A docking calculation may have one component superimposable and the second component represent an ensemble, and it is that ensemble that I would I like a measure of the total volume. Thanks! Andy
