We have an automation problem on a Varian spectrometer running under Solaris
2.5.1 and Vnmr6.1b. It is equipped with an SMS autosample changer w/Zymark
robot and a recently installed Nalorac autotuning probe and autotune module
capable of fine tuning on each sample. To accomplish this the usergo macro
was implemented to control autotune activity. usergo saves the acquisition
parameters, relocates itself appropriately to and from non-executable
positions to avoid infinite loops, performs the appropriate tuning
experiment, restores the previously saved parameters and then acquires the
spectra. This scenario worked for about two weeks.
Recently, the vnmr software locked up in the middle of an acquisition.
Termination of vnmr left usergo in the non-executable position which
disabled all autotune operations. Restoration of usergo to the executable
position restored autotune capability for non-automated runs. However, all
automated runs (autogo) now respond with no spectral acquisition and the
error message "No Data Requested" when usergo exists. When usergo does not
exist automation experiments run normally. We have attempted to resolve
this problem by rebooting the host and redefining usergo so that it only
echo's a message to a file. Additionally, we observed that with the
exception of the existence of the file curexp+'/psgdone' all parameters in
auto_au are identical from usergo to non-usergo automation runs. Short of
reinstalling the vnmr software we are out of ideas.
If anyone has experience with this type of automation or any ideas for
solutions to our problem, we would greatly appreciate hearing from you. We
have no illusions that our basic approach to programming for automation is
the best and would love to hear how anyone else has handled this situation.
