Hi Brian,
thank you for your reply.
I will try to propagate as many assignments as I can to see if it goes
faster!
Unfortunately, this is a rather slow process if you need to process several
data sets (as it is my case)...
Again, thank you for your advice.
Cheers,
Aldino

Subject: Re: Follow shift changes
In our experience, that's probably not unusual. Follow shift changes is
doing quite a lot of stuff under the hood - it's trying to work out where
your peaks are moving to as it goes - so can be a bit slow.
We have found that you can help it a lot by picking and propagating
assignments for as many peaks as you can first - after all you're probably
going to go and inspect the results afterwards, and it's usually easier to
do things right first time rather than mess about with deleting wrongly
picked peaks and disentangling mixed up assignments.
Drawing newly picked peaks is a slow thing, so it may go faster if you do
this with the spectrum not displayed.
1.3Ghz is on the slow side for getting decent performance out of analysis
in my experience.
