Hi Harry,
we are routinely using TS3.8.0 since >1 yr. on all our AV II / AV III HD
spectrometers (running Rocky Linux 9)
and have not seen any cortab problems when installing it (upgrading from
either TS3.5pl7 or TS3.7.0).
Since edasp shows the "green light", and you can run 1H acquisition, I'd guess
everything is alright with that cortab.
Something must be wrong in your Topshim setup, or in in the parameters sets
it is using (topshim1d1h) ...
Did you try running "expinstall" again to update all parameter sets?
Ciao,
Gerd

Hi folks,
Hoping someone can help me with cortab
I had to replace the controller PC and have installed Topspin 3.8.0 withoutissue.
I restored the previous installation files using nmr_save and everything appeared rosy.
However, when trying to shim on the sucrose sample (using 1H), I get this error:
and then this one:
Seems to be an issue with cortab yet the green ‘cortab available’ light
shows in edasp and one can acquire 1H data without issue:
There are a bunch of files in the <TSHOME>/conf/instr/<spec>/cortab/ folder
but the cortab window looks a bit sparse to me:
Can anyone point me in the right direction please?
Many thanks,
Harry
