Hi Elaine,
I have used NACCESS (https://www.bioinf.manchester.ac.uk/naccess/nac_intro.html) to calculate the SASA for a protein. It used the Lee & Richards (1971, J. Mol. Biol., 55, 379-400) method to calculate SASA.
I wanted to know whether chimeraX also uses the same method to calculate SASA or not. If not, then can you mention how the chimeraX method differs from the method used by NACCESS?
