HI Charlie
this all depends a bit on the version of software. Unless the pulsesequence
is written with the caldel and calph commands it is not easily possible.
This means topspin 3.5 or newer.
With all the methods below it is advisable to make a backup of the experiment
you have, just in case .....
Theoretically on can just type go instead of zg and the experiment should
pick up where it left off. I have never really tried it.
Juergen's suggestion points towards a correct way to get the rest of the
experiment acquired.
You can acquire the rest as a NUS experiment fntype = nonuniform sampling.
Your nuslist should include all the points that are missing. nuslists run
form 0 to (TD/2)-1 each entry acquires a complex pair. So your first would be
171,172 = (172/2)-1 = 85 and the last would be 199. Just make a list of
consecutive numbers from 85 to 199 store it in the VC folder "edlist vc". And
put the same name in the "nuslist" parameter. Set NUSpoints to 115 and run.
After the acquistion you "rser 1" from the new data set and write into the
original data set as wser and give 171 as the target then rser 2 and wser 172
and repeat 229 times :-( or write a script to do it.
my concern is that the more time passes between the first experiment and the
second there will be minute changes. The shims could not be the same, a slight
change in tuning might give a phase change and other subtle things that affect
the spectra. This means there will be a discontinuity between the first and
second set of FID's and that will become visible after FT.
Best regards
Clemens

Hi all,
Was asked by a user about this recently. My perhaps outdated experience tells
me that a 2D that is interrupted by a power outage or some other event cannot
be continued. But that's maybe just the simple answer. Figured if it can be
done, someone here would know how.
An example:� suppose TD1 is set to 400 but the experiment is interrupted
at 171. Can we set the first delay and phase cycling (and gradients and ...?)
properly and continue in obtaining 172 to 400, and then add that onto the dataset?
Clearly would be easier for some experiments than others. But for now, I'm
interested in whether there's some way to get topspin so it can do this for even
the simplest of 2Ds: i.e., acquire the 172 to 400 data. A separate issue, but
necessary, is then how to tag that onto the 1 to 171 data.�
