Spatial Calibration for Multiple Objectives

Multiple users of the scope may be running projects that require different types of objectives.  How to keep a spatial calibration for each and switch between them when necessary?

Scanbox now includes an “objective” configuration variable — a cell array of strings each with the name of a different objective.  Right now I have:


% objective list
sbconfig.objectives = {'Nikon 16x','Nikon 25x'};

Now, within the Knobby panel you will see a pull down list containing the objective names:

objectives

Select the desired objective before performing a calibration.  Once the calibration is finished it will be saved.  If a calibration is not present for a given objective the calibration button will read “No Calibration” and the mouse control will be disabled. If you change the objective, simply select the corresponding entry in the pull down list to apply the new calibration (no need to restart Scanbox).

When collecting data the info structure will include the objective name and calibration data:
