1 Download & Install ImageJ
The micaToolbox is an add-on for the standard NIH ImageJ (not FIJI). ImageJ can be downloaded for almost any operating system here. In general, use a version bundled with Java. Note the specific instructions for MacOS (path randomisation) which are flagged on the download page.
To install ImageJ simply unzip the contents of the zip file to a location on your computer. In windows, don’t unzip to Program Files. Use some other location on your hard drive (e.g. somewhere in Documents).
Double-click the “ImageJ” or “ImageJ.exe” file to run ImageJ. You can make a shortcut to this file if you want easy access.
2 Download & Install the micaToolbox
Download the latest micaToolbox version from the Downloads section of this website.
Unzip the contents of the zip file to your ImageJ/Plugins directory. If ImageJ is currently running, either restart it, or go help>refresh menus to load the toolbox.
