Hi André, Making a thick colored outline around an epitope on a protein surface is easier in ChimeraX using thick selection outlines. The link you mentioned from 2014 is from our old program Chimera which could only draw thin 1 pixel wide outlines. Here is an example in ChimeraX where I make a thick (10 pixel wide) red outline around some residues. open 2x7r hide ~/C atoms surface /C select /C:670-681 graphics selection color red width 10 Tom

Hello Chimerax,

I was wondering if there has been any progress on making outlines of specific epitopes in ChimeraX since this thread back in 2014? <https://www.cgl.ucsf.edu/chimera/data/outline-may2014/outlines.html> Thank you in advance.
