Yes, the definitions are taken from $GMXLIB/vdwradii.dat. You could either edit that, or possibly copy it to your working directory, edit there and g_sas should pick up the local copy. This mechanism works for other such files, so I'd guess it works here too. > Also if I am comparing the SASA for the enzyme in > three different simulations were only the ligand (for which all radii are > defined) differs, would this have a huge effect on the results? Your question is not clear to me.
