Hi Oli, Why yes, we have a "measure weight" command. However, it will only include the atoms that are present as coordinates (does not use sequence information), e.g. no missing segments or even hydrogens, unless you've added them. <https://rbvi.ucsf.edu/chimerax/docs/user/commands/measure.html#weight> I hope this helps, Elaine ----- Elaine C.

Hi,
Is there a ChimeraX command to calculate the molecular weight of the selection? It would be convenient for calculating how much ordered mass is present (especially for e.g. nucleic acid protein complexes).
Cheers Oli
