Hello I am new to using chimera and I have been struggling with one aspect. I'm trying to mutate one residue in my protein, by using the command swapaa leu :310, this seems to work nicely, To show the amino acid I then go in to "tools" then "sequence" and select this mutated residue and then go to "actions" then "atoms/bond" and "show" and the residue is displayed, however it is displayed as a block colour which I can't seem to change the colour scheme of the amino acid to match other residues which I've displayed nearby (e.g showing different colours (white/blue/red for different groups on the amino acid). i can easily change the block coulr of the whole reside but not to match the helpful scheme of he other displayed residues. However If I just pick an unmutated residue to display it shows it in the same style as the other residues (which is what I want for my mutated one) I hope that makes sense I couldn't find the answer in the help section Thank you very much for your time Jane
