Create the Connolly Surface in the.xtd file

Hello everyone,

After I ran a dynamic simulation of a polymer amorphous cell, material studio would output a .xtd file with many frames that showed how the polymer chains changed over time. Now I want to create a Connolly Surface for every frame in this .xtd file, so that I can watch the space between the polymer chains (which we call the free volume) change over time. It's very important to my research.

However, it seems that material studio can only create Connolly Surfaces for .std files. When a Connolly Surface is created for a .xtd file, each frame displays the same Connolly Surface. Obviously, different frames have different Connolly surfaces. So, is there any way, such as writing a script to achieve the function I want?

Thank you in advance and hope to get your help.
