0.2) so the initial trial won't take you too long. With a lower threshold weaker signals could be counted, but the risk of counting background noise as signals also increases.

'Threshold' changes the sensitivity on nuclei detection.

Use the line tool to mark distances, and click 'Measure Line Length' in the dialog to do so. These distances could also be measured on the image.

The 'width' parameter stands for the diameter of the nuclei in pixels, and the 'Minimum Distance' stands for the distance between two nearby nuclei.

or Drag&Drop, you will have to restart the Itcn plugin to count on them. If you opened some new images from File>open. If you want to use another unopened image, open it using the 'Open.' button.

Play around to determine the choices and parameters:.

Here I improved the original plugin a little bit so that it could be recorded by and used in ImageJ macro scripts. However, because the plugin is developed many years ago, it is no longer maintained and no detailed instructions could be found on the internet.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.
