Thanks this would work. I also tried the chimera workarounds to display surfaces of problematic molecules and found that changing the vdw radii vdwdefine +.01 as suggested solved the problem. The graphics and lighting of chimeraX are nicer though.

For example, open 1bxw mlp Documentation https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/mlp.html The PDB uses ChimeraX mlp for hydrophobicity images on their structure web pages, for example 1BXW image from the PDB web site below. http://www.rcsb.org/structure/1BXW Tom [cid:image001.png@01D3B556.66CC3430] On Mar 6, 2018, at 8:12 AM, Elaine Meng <meng@cgl.ucsf.edu<mailto:meng@cgl.ucsf.edu>> wrote: Hi Hernando, As mentioned in a recent post and also in the “Missing Features” on the download page, ChimeraX does not yet have coloring by attribute value, sorry. <http://www.rbvi.ucsf.edu/chimerax/download.html> <http://plato.cgl.ucsf.edu/pipermail/chimerax-users/2018-February/000212.html> In Chimera you could try making a molmap surface, coloring the atoms under that surface by attribute, and then using Color Zone to color the surface to match the nearby atoms. See #3 in the surface workarounds page: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/surfprobs.html> I hope this helps, Elaine ----- Elaine C.

I know it is possible to do it in ucsf-chimera but unfortunately surface calculation does not work in chimera for the files I am working on.
