Right, and you can even omit the "range" part because the color-value mapping is included in the palette, as described here: <https://rbvi.ucsf.edu/chimerax/docs/user/tools/alphafold.html#coloring> color bfactor palette alphafold You could use a different palette in the color command, if you like. In case you didn't know already: ChimeraX also searches/fetches from the AlphaFold Database of already-made models and applies this coloring. Just an alternative if you were going to that database, downloading files yourself, then opening them in ChimeraX. The search/fetch can be done with either the AlphaFold tool or the alphafold command. <https://rbvi.ucsf.edu/chimerax/docs/user/tools/alphafold.html> <https://rbvi.ucsf.edu/chimerax/docs/user/commands/alphafold.html> Best, Elaine ----- Elaine C.

Hi Daniel,

The pLDDT scores are saved in the B-factor column in the PDB files returned by AlphaFold. If you open them, you should be able to do "color bfactor palette alphafold range 0,100".

Hello everyone,

I have the results from some AlphaFold runs, is there a way to open them with ChimeraX, so I can see the plDDT, without needing to run Alphafold from within ChimeraX?

Thank you and best regards
