RE: [PyMOL] Super-smooth surfaces

[EPF \(E. P. Friis\) <EP...@no...>]

Hi Stephen

I also use smooth surfaces - for visualizing results from small angle
xray scattering, which is a low resolution technique. I use:

set solvent_radius, 4  =20
alter my_protein, vdw=3D4=20
sort
show surface, my_protein

Maybe you can set solvent_radius a little bit higher, but not much, as
you will get "holes" in the surface like you see. You can adjust the
"blobbiness" by changing the vdw size.


Cheers

Esben
