Failed loading Topspin Spectra

Analysis Version 3

Hello Vicky,

I encounter an error that prevents me from loading a Topspin spectrum (2rr file):

Loading “XXX\pdata\1\2rr” failed:
ccp.nmr.Nmr.Experiment.setTemperature:
PositiveFloat constraint float_value_gt_0 violated by value: 0.0

I suspect this is due to the Topspin data files didn’t record the probe/channel temperature (TE1 = 0 under the “probe” tab of status parameter, it wasn’t controlled by regular VT unit), and tried to manually change it, but I couldn’t locate any Topspin parameter file that contains this float_value_gt_0.

Is there a way to bypass this setTemperature check upon loading a spectrum? Or perhaps you could help me find where this parameter is checked or located?

Thank you,
Xiao

Hi Xiao

If you look for the TE parameter ($TE) in the acqus file in your Bruker data directory you can fix it there.

Best wishes

This is it! I missed the “$” sign so the search of that parameter didn’t work, now I’m able to change it and load the spectrum.

Thank you so much Brian!
