Hi chimera team, I use the Render by Attribute function frequently for models, but to date, I have only ever used it for rendering attributes determined 'internally' by chimera (hydrophobicity, AA conservation from an MSA etc). Is there a way to render residues by an arbitrary set of parameters? Imagine for instance, I have a csv that maps a residue number to a value (between 0 and 1). In my case this is antigenicity. ResNum, Res, Value 1, A, 0.927 2, T, 0.872, 3, W, 0.738 ... Can I read this file in via python/chimera commands and apply these values from an external file? Many thanks Joe Healey M.Sc. B.Sc.
