You asked the question about how to keep the transparency on a surface during trajectory playback in December and it was answered back then https://mail.cgl.ucsf.edu/mailman/archives/list/chimerax-users@cgl.ucsf.edu/... The same considerations apply to updating the electrostatic coloring each frame. To summarize the previous discussion when the trajectory goes to the next time step the surface is automatically recomputed and your coloring and transparency commands have to be done after that automatic surface recalculation. It is a bit tricky to make them happen after the surface recalculation and you should refer to the previous mailing list discussion to see examples of how that is done. Tom

update:
it seems that I could fix it via adding the transparency option directly to color:
color byattribute kdh sel target s palette sandybrown:coral:orangered novalue gray transparency 55
Just one extra question: how could I keep the coulombic electrostatic surface (calculated using the command coulombic) in the same manner for all frames ?

Dear ChimeraX users!
I am working on visualization of protein-ligand complex from MD trajectory loaded as multiframe pdb via open coordset true
Here is my script:
#coloring ligand options color ligand & C gold style ligand sphere
#transparency surface protein color byattribute kdh protein target rs palette sandybrown:coral:orangered novalue gray transparency protein 5 surfaces select zone ligand 4 protein transparency sel 55 surface
The problem is only in the transparency which could be set only on the first frame but then disappears when I browse movie. How could I modify my scipr to keep the transparency on all frames ?
Many thanks in advance !
Enrico
