Yes, coumarin is not sperical and so its diificult to calculate the radius
by determining its volume.
I am given task to calculate the vdw radius of a diacetoxy coumarin molecule
and I happen to find that  PYMOL has an option to label vdw radius. But the
PYMOL could label vdw radius of individual atom. Can anyone suggest me how i
could determine vdw radius using any software.

Thank you
