Hi Saverio, As Greg said, you cannot use a ChimeraX tutorial for Chimera. They are two different programs, and some of the commands are different (Chimera does not have "color byattribute" etc.) Elaine ----- Elaine C.

Are you using Chimera or ChimeraX? You're asking your question on the Chimera users mailing list, but the commands you gave are for ChimeraX.
Chimera is no longer being developed. So the recommendation is to switch to ChimeraX, https://www.rbvi.ucsf.edu/chimerax/. For a synopsis of the advantages of ChimeraX over Chimera, see https://www.rbvi.ucsf.edu/chimerax/docs/user/advantages.html.
HTH,

Hi, I'm using the Attribute Assignment Files tutorial with the commands: open 1pho open kdHydrophobicity.defattr color byattribute kdHydrophobicity palette ^RdYlBu select ::kdHydrophobicity>2.0 I've only substituted 1pho with 1caz. For the command: color byattribute kdHydrophobicity palette ^RdYlBu I receive the error "color byattribute is undefined" with different version of chimera. Any suggestions? Thanks. Saverio
