12.2 TopSpin troubleshooting
If your current TOPSPIN session has a problem, you can find in this chapter some
instructions how to get rid of this situation.
In order to stop T
OPSPIN in case of any problems, the first thing to know is, that it
is using a client / server structure. It is possible to start more than one client. This
feature is used for the remote control but can also be very useful for troubleshoot-
ing!
• The client can be stopped without touching a running acquisition.
To get rid of a T
OPSPIN problems follow the description below. These steps are
increasingly drastic. Please note that this procedure is only necessary in case of
any problems as TopSpin does not react anymore.
1. Create debug information and send it to Bruker. For this follow the instructions
in chapter 12.2.1
2. Open a Linux shell and start a second T
OPSPIN graphical user interface with the
command:
<TOPSPIN_HOME>/topspin -client
<TOPSPIN_HOME> is the TOPSPIN installation directory, in a default installa-
tion this is /opt/topspin
Does the second T
OPSPIN graphical user interface works fine?
• Yes? The problem is solved you can go ahead with T
OPSPIN.
