Talk:Events - DatLab

MitoPedia O2k and high-resolution respirometry: O2k-Open Support

Description

DatLab shows events as vertical lines in graphs and reports them in the experimental log. DatLab events show when the user performed a step of a DatLab protocol, when a part of the O2k changed its status or setting (e.g., illumination on/off), when a user-defined limit was met (like the 'Lower O₂ limit' or when an error occurred. Events can also be used to save arbitrary user notes. Most widely they are used during application of DatLab Protocols.

DatLab 8

Event types

User events - any content allowed, can be modified.
Protocol events - preferably set by clicking on the Protocol panel, can be modified.
Instrument events / TIP2k events - like Stirrer on/off, light on/off, TIP2k injection starts... - cannot be modified.
Notification events - notifications are set by the user (e.g., Lower O2 limit) - cannot be modified.

Add an event

during a DatLab Protocol click on the next event shown in yellow in the Protocol panel. The event will appear in the graph with the appropriate name.
Strg + left mouse click in the graph area.
F4 adds an event at the end of the graph.

Modify events

left mouse button on the event name in the graph or in the Protocol panes opens the Event information window.
rigt mouse click on the event line opens a dialog box with the options 'Delete', 'Edit', or 'Drag' the event.
Choose to show or hide events in the Graph options.

Options after right mouse button click on event name

A box appears after selecting 'Drag event' as a handle for dragging

Event information window in DatLab 8

Event information window

Focus on the part highlighted in yellow. The table on the right side appears as an option list in experiments run with the aid of a DatLab Protocol. If an DatLab Protocol is active, you can add an event and select the protocol step to prefill the event fields. The event information window exclusively edits the selected event, it does not serve as an editor of other events in the file / experiment.

Name, definition: chose a short name for the first field and describe details in the second.
Concentration: if a solution is added, note the concentration.
Titration volume [µL]: this field is important, if 'volume correction' is selected for calculation of the specific flux (see Flux / Slope).
Time: can be adjusted for user or protocol events, not for instrument or notification events.
Comment: note your comments or find explanation of instrument or notification events.
Chamber: Events added to both chambers are black, in Chamber A only they are magenta and in Chamber B only they are green
Delete: only user events can be deleted.

DatLab 7

Add an event

during a DatLab Protocol click on the next event shown in yellow in the Protocol panel. The event will appear in the graph with the appropriate name.
Strg + left mouse click in the graph area.
F4 adds an event at the end of the graph (i.e. at the time you add it) and opens the Event information window during an active measurement.

Modify events

left mouse button on the event name in the graph opens the Event information window.
right mouse button on the event in the Protocol panel opens the Event information window as well.
Events cannot be dragged. They can be edited via the Event information window to some extent. Instead of dragging it, delete it and create a new one.

Event information window in DatLab 7

Event information window

Focus on the part highlighted in yellow (in some events the rest of the window is even missing). The table on the right side appears as an option list in experiments run with the aid of a DatLab Protocol. The protocol steps can be selected to prefill the event fields. The event information window exclusively edits the selected event, it does not serve as an editor of other events in the file / experiment.

Name, definition: It is recommended to edit event labels with a minimum number of characters, and to explain the abbreviation in the 'Definition' box.
Concentration, Volume: The final concentration and titration volume can be entered into the corresponding boxes, if the event relates to the titration of a substance.
Time: cannot be edited. If an event is at the wrong place, delete it and create a new one.
Comment: A short comment can be entered to describe the event in detail.
Chamber: Events added to both chambers are black, in Chamber A only they are magenta and in Chamber B only they are green
Delete: since dragging is not possible, delete an event at a wrong place and create a new one at the right place.
