[chimerax-users] measure neighboring distance of histidine side chain

Dear all, I am interested to get a list of distances between histidine residues in my built model. Because I would like to see which crosslinker can potentially help to maintain the structure better during purification. I have noticed that I can measure one residue in chain A to all other atoms in chain B using contact function, however, I want to get a list of distances between any histidine imidazole (neighboring distance), is there a way to do that in ChimeraX? Super thanks in advance. Best, Hong
