[chimerax-users] view and the center of mass of the selection

[Enrico Martinez]

Thank you Elaine!
I did it like this:

# calculate com for the ligand
define centroid ligand name lig_com
# then view the new model of the centroid
view #1.1.3 orient clip false; turn z 90; turn y 45; turn x -90; turn x 77
wait

one question: I have not found a way to use the "view" with the name
of the model "lig_com", always operating with the model number
(#1.1.3). May I use "lig_com" for the same operation?
Cheers
Enrico
