Hi Sasha, Yes, this is commonly done by people who want to define custom attribute values. We have a simple text format for reading attributes into ChimeraX. See "attribute assignment files" for the format description: <https://rbvi.ucsf.edu/chimerax/docs/user/formats/defattr.html> You can open them as "format defattr" or filename *.defattr with the "open" command, which will automatically assign the attributes as defined in the file. Sorry, ChimeraX doesn't read Pymol CSE files. I hope this helps, Elaine ----- Elaine C.

Hi All, is it possible to import residue attributes from a text/csv file? For instance, I have some data calculated at an external server, and the output is per residue in CSV format. I would like to view it as color-coded molecule, using the command "render by attribute". Is it possible? Or if not, do you know some workaround?

Also, I have these data in a pymol file but I don't use pymol. Is there any way how to read a pymol (CSE) file into chimeraX?

Best Sasha
