Hi everybody,
Has anybody experienced this before? I have experiments failing occasionally
at the ATM step in ICON-NMR, followed by all subsequent spectra failing at
the ATM step. Restarting Topspin will fix the problem, and I can re-submit
the failed experiment(s). ICON-NMR will give an error that reads something
along the lines of "Cannot run single acquisition: cpp error detected in
/root/.topspin-BladeEpu/local_acqu/tuneDirs/[datasetname]/1/lists/wobble/pp_drx
Wobbling error. Details: ATM Failed."
Sometimes I see a variation on this, where the first experiment will complete
successfully or almost successfully but with an X under "Proc." In either
case there is an error message "Cannot run single acquisition: cpp error
detected in /root/.topspin-BladeEpu/local_acqu/tuneDirs/[datasetname]/1/lists/pp/[pulseprogram]"
but also "audita.txt file not in data set," or "/path/to/fid No such file or
directory." In both cases, subsequent experiments fail with ATM errors.
My best guess based on these messages is that this is caused by a brief failure
in communication between the console (a NEO) and computer. Briefly unplugging
the ethernet cable during ATM gives a similar result (spectrum and subsequent
spectra fail, restarting Topspin fixes) but with different error messages
(something like "ATM already in progress"). Replacing the ethernet cable
does not stop the issue. It's happening roughly weekly, so manageable but
annoying.
My recollection is that this began shortly after updating from Topspin 4.1.4
to 4.3.0, not sure if this is relevant. Any insights are appreciated!
