Hi Wooghee,

Always appreciate your prompt responses!

So I did what you said regarding the saved file, as in opening directly as a uscf file, it did open it but without the assignement although it said loaded Expt.save 198 peaks.

So I did this several times, I even opened the 2rr files, but no luck. So restarted my PC etc. and no luck again.

Then, again, I did the same thing with my second HSQC, and it worked fine.

So what i did is delete the non-working .ucsf file and created a new one, opened it and did .ta and transfered the peaks: and it worked well.

Clearly something is wrong but i dont know what?

Many thtnaks again
