[gmx-users] g_sas for martini coarse-grained particles

[Sanku M]

Hi,
   I am trying to estimate the solvent accessible surface area of  hydrophobic 
tails of  a martini DPPC  lipid bilayer . I was going to use g_sas for that. 
But, I observe that this tool gets the vanderwal radii from vdwradii.dat file. 
But, since the particles in the martini lipids are united-atom types, I was 
wondering what will be a reasonable radius to use for hydrophobic tail particles 
of a martini lipid ?

Thanks
Sanku
