Hello everyone,
I hope you are fine.
I want to plot the pore size distribution of a polymer structure.
I want to know the following steps are correct?

Tools --- atom volumes & surfaces---create Connolly surface
---creat segregate--- Analyze segregate field---- segregate separation

Is the final step (segregate separation) the right option? Could you please tell me what the axises units are?
I would appreciate it if anyone could guide me.
