Start parameter optimization by typing popt in the command line. The popt win-
dow will appear.
Figure 4.16. The popt Window
Use optimize step by step, parameter p1 to optimize parameter p1, optimum
posmax to find the highest signal intensity (90 degree pulse) for the given value of
pl1w or pl1,and varmod lin to use linear increments for optimization. The value
for group is not used for optimizing only one parameter and the number of exper
-
iments nexp is set automatically when clicking on the save button. Then save ta-
ble by clicking on the save button and click on start optimize to start the
optimization procedure.
The parameter value obtained by the program is written into the parameter set of
the actual experiment at the end of the optimization.
In order to stop the execution of popt use the skip or stop optimization buttons.
Skip optimization will evaluate the obtained data as if popt had finished regularly
and writes the parameter into the parameter set. Stop optimization will stop with
-
out evaluation of the data. You can also type kill in the command line and click on
the bar with “poptau.exe” to stop optimization. This will work like stop optimiza
-
tion.
Popt will generate a data set, where the selected expansion part of the spectrum
is concatenated for all different parameter values (in this case, for p1). It will have
a
procno around 999. To achieve this, processing parameters are changed ap-
