FAQ (Frequently Asked Question)

How can I color amino acids by they name or a color code?

Unfortunatly Pymol does not have a built-in function to do that….
Fortunaly we can create our own functions =D
I’ve made a script to color amino acids by a color-blind adapted color code [1].

  • Download the script below
  • Refer to this page on the Tutorial section if you don’t know how to execute it.

 I Can’t manage to load a PDB (ascii error or Unicode Error).

Pymol doesn’t allow a non-classic character on the file path (accent, space etc…). Change the location of your pdb file or script file.
