Edit-on-Sequence Parameters
Links
Introduction
Edit-on-sequence parameters will be displayed for edit when a new Sequence is started (similar to the Edit-on-start Parameters that appear when a run is started). Edit-on-sequence parameters may be defined in the /Experiment ODB tree in an optional Edit on Sequence subdirectory in the same way that Edit-on-start Parameters are defined in the Edit on Start subdirectory.
A sequence can only be run from the mhttpd Sequencer Page (not from odbedit). Edit-on-sequence parameters are displayed (Figure 1) when the Start Script button is pressed.
Creating edit-on-sequence parameters
Create the subdirectory edit on sequence in the /Experiment ODB tree and fill it with the required parameters in the same way as described for creating edit-on-start parameters
Example
An example of edit-on-sequence parameters defined in the /Experiment/edit on sequence ODB subtree are shown below using odbedit. Edit-on-sequence parameters can be linked to Parameter comments in the same way as edit-on-start parameter comments.
The defined edit-on-sequence parameters are displayed for editing in Figure 1 below.
