A set of three ImageJ plugins to quantify ciliary shape, length, and fluorescence in 2D, 3D, and 4D images. Scroll down for information on how to use, cite, report ideas, issues, improve CiliaQ. Visit our CiliaQ wiki with Tutorials and a Q&A section or try out CiliaQ using an example image.

The ImageJ plugins are published along:

Jan N. Hansen, Sebastian Rassmann, Birthe Stueven, Nathalie Jurisch-Yaksi, Dagmar Wachten. CiliaQ: a simple, open-source software for automated quantification of ciliary morphology and fluorescence in 2D, 3D, and 4D images. Eur. Phys. J. E 44, 18 (2021). https://doi.org/10.1140/epje/s10189-021-00031-y

Included tools (ImageJ plugins)

• CiliaQ_Preparator: An ImageJ plugin to preprocess and segment images for CiliaQ analysis.
• CiliaQ_Editor: An ImageJ plugin to edit the segmented channel in images output by CiliaQ_Preparator before analysis with CiliaQ.
• CiliaQ: An ImageJ plugin to quantify the ciliary shape, length, and fluorescence in images that were pre-processed with CiliaQ_Preparator (and eventually edited with CiliaQ_Editor).

Tools for post-hoc analysis of the output data

See our R scripts for combining results produced with CiliaQ.

Licenses

The three CiliaQ plugins are published under the GNU General Public License v3.0.

Some CiliaQ plugins include packages developed by others, for which different licenses may apply:

• The packages ciliaQ_skeleton_analysis and ciliaQ_skeletonize3D in CiliaQ have been derived from the plugins AnalyzeSkeleton and Skeletonize3D, respectively (Both: GNU General Public License, http://www.gnu.org/licenses/gpl.txt, author: Ignacio Arganda-Carreras).
• The package ciliaQ_jnh.volumeViewer3D in CiliaQ represents a customised version of the code from Volume Viewer 2.0 (author: Kai Uwe Barthel, date: 01.12.2012). Customised variants of the code are marked by additional comments. The original code was retrieved from https://github.com/fiji/Volume_Viewer, which is published under the license "Public Domain" in the software project FIJI.
• The package ciliaQ_Prep_jnh.canny3d-thresholder in CiliaQ Preparator represents a customized version of the canny3d-thresholder (GNU General Public License v3.0, author: Sebastian Rassmann, GitHub repository: https://github.com/sRassmann/canny3d-thresholder).
• The package ciliaQ_jnh.stern_library.optimization in CiliaQ contains a copied version of the HungarianAlgorithm implementation by Kevin L. Stern (copyrighted 2012) that is used as permitted by the very permissive terms printed in the file. The original code was retrieved in August 2024 from https://github.com/KevinStern/software-and-algorithms/blob/master/src/main/java/blogspot/software_and_algorithms/stern_library/optimization/HungarianAlgorithm.java.

Some functions of CiliaQ Preparator (Hysteresis thresholding, Canny3D) require additional installation of the '3D ImageJ Suite' to your ImageJ / FIJI distribution. The '3D ImageJ Suite' is licensed via a GPL - for license details visit the main page of the '3D ImageJ Suite'.
