Hi ChimeraX teams,
Can you guide me to use the  atoms-spec for info distmat command.
I want the output in the chimerax log to list out distances between the drug compound and the amino acids side chains and only display the distances below than 4A.

For now, what I have got, the output includes distances between atoms in the drug itself and atoms in the amino acids itself and I don't want that. 
Only display distances between atoms of the drug and the amino acids side chains.

The protein and drug details: PDBID= 4YVP with drug compound DEX
The drug binding site distance is below than 4A.

The command that i have try are:
  1. info distmat (protein & sideonly) | :dex ::num_distance< 4
  2. info distmat (protein & sideonly) | :dex
  3. info distmat (protein & sideonly) & (:dex) distance < 4

Hope you could help me with this.

Regards with thanks, 
Aida.
