Hi, I am new PhD student using ChimeraX and I am very interested in learning how to work with this program.

I am trying to introduce some mutations in my protein in some specific amino acids that I have selected. When I introduce an Alanine in my position of interest (using dunbrack) I have no issues, but when I try any other amino acids (as Phe or Thy) the program has no problem giving me the prediction for the rotamers, but I have some issues. After select some of the most probable rotamers, all the amino acids of my protein change to that kind of amino acid (not just the specific one that I have selected).

Another problem is that I have is that when I select a specific atom of an amino acid, the program also select similar atoms but in all the others amino acids of my protein.

I really hope that someone can help me with these issues.

Thank You very much
