[Chimera-users] Visualizing specific atoms in autodock-vina output

I am trying to investigate the protein surrounding a docked (autodock-vina, alpha chimera 1.1 build 40505 linux 64) ligand. I am interested in the environment of specific atoms of the ligand. With command sel #1.1@N z<5 I can investigate the protein at 5A from BOTH nitrogen atoms of model 1.1. How to select one of the two existing N atoms in the ligand? Same questions for other ligand atoms (there are many O-atoms) Is that possible without elaborating the vina output? thanks francesco pietra
