ColonyDoc-It Imaging Station 36
Using the Software
Changing Filter Settings
To reduce user initial set-up time, filters were created to count “true” colonies and remove inherent defects from the
sample plate that would (without the filters) be included in the total colony count. The filters may prevent a colony
from being counted based on some critical parameters.
To set new filter parameters, click onto
the Show Results Window > Filter >
Filter class and drag the pointer to the
filter class to change.
A new Filter Colonies window will
appear with the following parameters:
Area, Perimeter, Avg Diameter, and
Circularity.
The predefined ranges are defined.
Each parameter can be changed to
accommodate a wide variety of sample
types.
The new range can either be inclusive or exclusive. Click onto the Keep Range or Exclude range depending on
sample requirements.
Enter the values to keep or exclude. Click OK.
The software will recount the colonies based on the new filter values.
