hello I was trying to use the unaliasing propogate function today, and it doesn't seem to work. I select a bunch of peaks in a strip, unalias one of them to the correct ppm, then right click on that peak and select unaliasing propogate. I get a message asking if I really want to do that, and giving the position of that peak (correctly). I select ok, it then goes right ahead and changes the aliasing of the peak I unaliased back to 0 without changing any of the other peaks at all. Has anyone else got this to work? Am I doing something wrong? Also I have recently been finding that analysis gradually uses up more and more memory in the course of a day to the point where it starts eating into the swap and getting really slow. I don't remember this being the case before so I was wondering is this normal behaviour, and is there anything I can do about it other than quit and restart? thanks, simon
