Hi All,

I was wondering if anyone has a preferred way of calculating the polar and apolar surface areas for a macromolecule with ChimeraX? I've tried deleting all of the solvent and then using the command "measure sasa @N @O @S" for the polar surface area and then "measure sasa @C" for the apolar surface area, but the calculation for either comes up with a number too close to the total surface area, i.e. apolarSASA + polarSASA > totalSASA. So clearly I'm not approaching this problem correctly.
