| As of March 2019 there is a feature to acquire an overview acquisition. This is useful when the entire sample is many times larger than the instantaneous field of view. The overview image is a 2D image representing a thin slice of the sample which can be collected relatively quickly. After acquisition, a rectangle is placed on the overview image representing the current stage position, and this rectangle moves with the stage as long as positions are being updated. It is not intended for use with a Z grid but only XY grid. | The overview acquisition is useful to orient the user in the context of the larger sample when it is many times larger than the instantaneous field of view of the microscope. It creates relatievly quickly a 2D overview image representing a thin slice of the sample. After the overview acquisition runs the overview image is displayed. A rectangle overlay is placed on the overview image representing the current stage position, which rectangle moves with the stage as long as positions are being updated. |

| Some settings for the overview acquisition reside on the "Data Analysis" tab. These include the downsample factor for XY and for slice spacing. The fractional thickness specifies how much of the entire image will be max projected to form the overview image. You specify a channel and a side to run the overview acquisition with. | Overview acquisitions are intended for use with an XY grid only, not a Z grid. Running the overview acquisition uses the current settings of the XYZ grid GUI for X and Y (if they are enabled) and will overwrite any existing position list. |
