Selecting Zone of Inhibition Detection Colonies for Picking
After you adjust and refine test images, the system captures and processes a higher-resolution
image using the test-image adjustments and then displays the Feature Selection window.
In the Feature Selection window, pickable objects show in yellow and unpickable object show
in red. A colony can be considered unpickable if it is too close to the edge of the receptacle or it
does not match the selection criteria.
To view the details of a colony, hold the cursor over the colony to display the properties of that
colony. If a colony has not been selected as pickable, the reason for the exclusion shows in red
text.
Drag the Zoom slider below the image to get a closer look at the image, and drag the Contrast
slider to change the contrast between the objects and the background.
To save the image in .bmp, .jpg, or .png format, click Export Image.
To select a smaller region of interest (ROI) in the image, draw a polygon around the region.
When you draw a polygon on the image, the system detects and picks colonies only from within
the defined region of interest.
To draw a polygon, click the Draw Polygon icon and then click the image to define the
corners of the polygon.
To resize the polygon, drag the blue boxes on its corners.
To remove the polygon, click Delete Polygon.
