The midas documentation has moved. See [https://midas.triumf.ca/docs/develop/features/monitoring_and_control/sequencer/scripting/#defining-parameters Defining parameters] on the Sequencer: scripting page and [https://midas.triumf.ca/docs/develop/reference/reference/odb_keys/#experimentedit-on-sequence /Experiment/Edit on sequence] on the ODB keys page for the new documentation about edit-on-sequence parameters.

== Introduction ==
Edit-on-sequence parameters will be displayed for edit when a new [[Sequencer|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 {{Odbpath|path=Edit on Sequence}} subdirectory in the same way that
[[Edit-on-start Parameters]] are defined in the  {{Odbpath|path=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|Figure 1]]) when the  {{Button|name=Start Script}} button is pressed.
 
 
== Creating edit-on-sequence parameters ==
Create the subdirectory {{Odbpath|path=edit on sequence}} in the [[/Experiment ODB tree]] and fill it with the required parameters in the same way as described for [[Edit-on-start Parameters#Creating ''edit-on-start'' parameters|creating edit-on-start parameters]]
 
== Example ==
An example of edit-on-sequence parameters defined in the {{Odbpath|path=/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 Parameters#edit-on-start parameter comments|edit-on-start parameter comments]].
 
 
The defined edit-on-sequence parameters are displayed for editing in [[#Figure_1|Figure 1]] below.

The midas documentation has moved. See Defining parameters on the Sequencer: scripting page and /Experiment/Edit on sequence on the ODB keys page for the new documentation about edit-on-sequence parameters.
