Hi Dave,
Thanks for the quick reply. We just want to calculate SASA (solvent accessible surface area) for the amide NH groups of protein backbone (no GBSA calculations are intended to be performed). We want to use this property to predict the hydrogen exchange rates of the protein backbone amide groups with solvent water molecules. For this kind of situation, are the bondi radii also suggested?
Best regards,
Pengfei
