However, because the plugin is developed many years ago, it is no longer maintained and no detailed instructions could be found on the internet.
It could also be downloaded from the developer's web page (This version actually works better). The original plugin is developed by the Center for Bio-image Informatics at UC Santa Barbara, and released on the ImageJ website. This is a modified version of the ImageJ plugin ITCN.

Pressing the keyboard key "Enter" in any of these input fields will delete the previously saved *-RoiSet.zip and recount the image with the new settings, saving a new *-RoiSet.zip when the image is closed or replaced by "Open next". Size fields: Allows setting the minimum and maximum limits for the size of colonies that the user wants to detect and count. About: Shows the "About Colony Counter" message window. Delete colony: Activates/Deactivates the "Show all" function of the ROI Manager, allowing selection of a colony by clicking on it's number on the image, and then deleting it by pressing the keyboard letter "d". The last value in the "Results" table and the *-RoiSet.zip file are updated. Add colony: Adds the currently selected area as a colony allowing correcting the automatic count.

The plugin's interface is simple, on the left are the functions buttons, on the right the input fields for the settings.Įxcept for the "Delete mode" and the "About" buttons, all the others have a keyboard shortcut (visible inside square brackets on the button's name) that can be used when the mouse cursor is placed on the image. When the image is closed, a file named *-RoiSet.zip is automatically saved in the current folder, so that the next time the same image is opened, the plugin won't have to recount that image and can simply load the results from the *-RoiSet.zip. The obtained values are displayed in a "Results" table and can be saved in *.xls file format. This plugin was created to count bacteria colonies from agar plates images.
