Hsin,
to get reproducible integration ranges, save the integration region in
one dataset and then read it into the other.
To save integration region in Topspin: Type "wmisc intrng", select
"Write New", specify a filename and click Ok.
To read an integration range: Type "rmisc intrng", select the file you
just created, and click "Read".
