licensed under proprietary terms, incompatible with the <a href="/licensing/gpl">GPL</a> and similar licenses, with <a href="/software/fiji">Fiji</a> having been granted special permission to redistribute them:</p> <blockquote> <p>Date: Mon, 26 Jul 2010 10:58:20 +0200<br /> From: Michael Unser</p> <p>[…] we are happy that Fiji distributes our software: you have my formal authorization for this (in my quality of lab chief). “You’ll be free to use this software for research purposes, but you must not transmit and distribute it without our consent”: this means that from now on, you are authorized to distribute any ImageJ pluging listed at https://bigwww.epfl.ch/algorithms.html since you have our consent.</p> </blockquote> <p>Fortunately, the plugins have since been updated to use an <a href="https://imagej.net/licensing/open-source">open-source</a> license: the <a href="/licensing/gpl#gnu-general-public-license-v3">GPLv3</a>:</p> <blockquote> <p>Date: Mon, 3 Apr 2023 10:54:54 +0000 From: Michaël Unser<br /> Subject: BIG’s plugins for FIJI / licenses</p> <p>[…] I am pleased to confirm that all of our software are open-source, in line with the FAIR principles promoted by EPFL. Our licensing follows the GPLv3 and we are currently updating our terms to reflect this.</p> <p>In addition, we also strongly encourage users to properly cite our research papers in any publications that make use of our software.</p> </blockquote> </div> </div> </section>  <section id="footer"> <ul class="icons"> <li><a href="https://forum.image.sc/tag/imagej" class="icon alt"><img
