[Chimera-users] accessible surface area for electron density maps

[Elaine Meng]

Hi Murali,
As far as I know, there is no definition of accessible surface area  
for an electron density map (and thus no way to calculate it in  
Chimera), only for atomic structures.  I'll describe how to get it  
for atomic structures in my next message, replying to David.
Best,
Elaine
