[Chimera-users] the problem how to show distance

[Elaine Meng]

Dear Kenji,
You have many more than 2 atoms selected.  You can see from the green outlines that you have the whole residue of Trp selected (multiple atoms) and 1 atom of the ligand.  You need to pick only  1 atom from ligand and 1 atom from Trp.
Best,
Elaine
