Cannot access data for this instrument from computers in lab.
The data file access problem is now fixed
machine craps out
cpp: /opt/topspin/data/jamory/nmr/protonstd/1/pulseprogram.pre: Read-only file system
1 precompilation error detected in /opt/topspin/exp/stan/nmr/lists/pp/zg
execution aborted
Error: during opening of /opt/topspin/data/jamory/nmr/protonstd/1/pulseprogram.pre: No such file or directory
I did not see a specific issue with the sample seating as of this writing. It could have been a hanging process with the BSMS keyboard that led to the spurious display that said “missing”. You can always start ‘bsmsdisp’ at such times and confirm that the sample is indeed seated properly. ‘bsmsdisp’ is the software equivalent of the BSMS hard keyboard. The lock nucleus missing could be related to the parameter LOCNUC set to OFF in your parameter set. I will look for recurrence of this to see if there is anything more involved.
Sample up/down light showed missing when I came up to the instrument even though there was a dummy sample inside. when I put my sample in, sight never turned green to show sample down and stayed at missing.
Upon typing lock, saw message ” lock nucleus not on”. Did not know how to fix that.
I checked a while ago and the file server seems to be functioning as expected. Please try again.
Can’t access data remotely from lab- can access other instruments just fine.
500 back up and running
Computer is not working. Cannot use the instrument.
Logged on and got an error message:
mod lockserver
error opening spect:/dev/tty03
timeout
Closing that error message gave another one:
Unable to get data from lock server.128.95.172.212
Tried to log out and log in again and got the same error. Lock status is listed as “not available”
It was also not possible to open any old data sets form the instrument computer.
