[Chimera-users] multiple mutations

Hello: How can mark (change color) for ~ 100 mutations at once? Is it possible to write a "code" for that? I would like to have random (different) colors for every mutation. It the case, if mutation lay down very close and same color would make it difficult to tell them apart. Another question: How to add a label like "V75" (Amino acid and position, not "V75.A") with all with black color (not the same color that marks mutation on 3D structure)? Thank you. Sincerely, Andrew
