[gmx-users] vdw radii in g_sas

[rajat desikan]

Hi All,
In the local copy of vdwradii.dat for g_sas calculations, the vdw radii are
very approximate.

Eg. C = 0.15 nm in vdwradii.dat, whereas ffnonbonded says sigma = 0.367 nm
=> vdwradius=0.185 nm

Is it prudent to replace the values in the local vdwradii.dat with the
vdwradii derived from ffnonbonded values? I would love to hear your
thoughts/suggestions.

Thanks,
