Hi Justin and thank you for your kind update and I just copied the command from the tutorial and pasted this command into my iTerm, here is the entire command and output below:
Joels-MacBook-Pro:Tutorial4 joelsubach$ gmx distance -s md_0_10.tpr -f md_0_10_center.xtc -select ‘resname “JZ4” and name OAB plus resid 102 and name OE1’ -oall
