Problem with sequential backbone assignment

I have assigned the CAi-1, CAi, CBi-1 and CB. I followed each step of the turtorial. When I step to the Connecting NmrResidues (step 5E), I found the interface of myCccpNmr is not the same as the the tutorial. The tutorial asks me to strip the label `NR:@-55` on the spectrum display and drag it to the <<< icon in the other spectrum. However I cannot find label as well as the triple arrow on my UI. Can anyone esle help me to solve this problem?



the arrows have changed to the little orange arrows highlighted in your second figure. So you should be able to drag the NR:@-.33. label onto one of the orange arrows. See attached figure.

Best wishes,
