Please can I have some ideas as I just don't get it. We usually come here, after countless Google searches, not as a first resort =)

What is the center of mass of an atomic coordinate of protein? I'd like to program it using biopython

Is there a formula for it? Why is this important? How is it related to the mean?

With all due respect, I am not convinced that you have done countless Google searches. A single Google search with "center of mass protein biopython" returned this as a first hit. There is a section "Coarse Grain Structure" towards the end that shows a simple Biopython solution:

from Bio.Struct.Geometry import center_of_mass

There is no guarantee that that function is correct...

Biopython is quite a mature library at this point, why would you assume that it is incorrect? (I haven't looked at the source myself)
