[chimerax-users] Setting transparency for multi-frame PDB

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
