[ase-users] sorting by number of atoms

[Kim Nicoli]

Hello,

I am new to this ASE and I am trying to become confident with both the
environment and database. Therefore, I have a simple question:
Is there a simple and straightforward way to sort (and save/update  after
the sorting) a database of atoms over the *number of atoms* in a decreasing
order? This is to say that I would like the longest molecules to be on the
first row and so on.
I went through the documentation and I guess this should be feasible and
not that complicated but I am not getting the right syntax to do it.

Thanks for any help!
With my best regards,
