Observe

The observe workflow allows you to observe a collection of points over time.

Start the workflow to choose positions you want to observe or reuse an already defined collection of points (e.g. from your previous injection).

After selecting your points to observe, configure the workflow:

Observe Workflow

Note

You cannot control the Omnium manually when the observe workflow is running.

Note

You can cancel the workflow at any time. The results of a canceled observation are not lost and are available in the result history.

Actions

These are the currently supported actions to repeat for each point:

Action Description
Record image Takes pictures of the current point according to the configured imaging settings. If multiple imaging settings are selected, they will be applied in the order how they are displayed. The pictures will be available in the result history. If two or more images are recorded per point an additional image will be generated with overlaid frames.
Record image (User-confirmed) Same like “Record image” but stops the workflow until he user clicks the “Continue” button.
Wait for user confirmation Moves to the point and stops the workflow until the user clicks the “Continue” button.

Imaging options

It is possible to apply different imaging settings during the selected action and while waiting for the subsequent repetition (“idle” time) to begin. The settings can be created and edited in the preset tool.

The Current settings entry captures imaging options when the observe step is opened.

Parameter Description
Settings to apply during action Allows selecting one or more presets to be applied during the action
Create additional merged image Enables or disables creation of a merged image. This is only available when multiple presets (during action) are selected.
Settings to apply during idle time This preset is applied when waiting for the next repetition

Multiple presets and image merging

When multiple presets are chosen for the selected action, the action will be repeated for each of the presets at each selected position. If multiple images are recorded in this way, the Create additional merged image switch controls whether the software automatically creates an additional image composed of these images.

Probe retraction options

You can choose different positions (height) for the probe using the Retract cantilever during observation option:

Probe position option Description
Keep Keeps the probe at the current height. In this mode, observation is only possible within the current sample area.
Retract Fully retracts the probe.
Observation height Keeps the probe above the plate at the configured observation height. This will provide more light than the Retract option.

Parking options

Unless the probe is kept at its current height for observations, it can be parked at a different position during idle time. This may be useful for prolonged observations to prevent the probe from drying. Use the Park probe while idle option to open the configuration dialog, select a target sample area and Parking height.

Note

The probe will also be moved to the configured park position at the very end of the observation workflow.

Note

When the calculated idle time is less than 5 seconds, parking is skipped.

Repetition

To repeat the selected action multiple times, set the Number of repetitions and Repeat actions after options. Each iteration will perform the selected action once for each point.

The repetition interval specifies the time between the start of two successive iterations. Therefore, if it takes longer to perform the selected action on all points than specified in Repeat actions after, the next iteration is started immediately after the last point is processed.

Focus option

When observing the points with the workflow, the focus level of the microscope can be restored to the one when the position was selected using the Restore focus level option.

Note

If the lens of the microscope has changed since the position was selected, the focus might not be accurate anymore.

Note

This option is only available for motorized microscopes
