Meiosis bar tool is an ImageJ macro used to analyse images of synaptonemal complexes of spermatocytes chromosomes spreads. It uses:

• Jerome Mutterer's Actionbar plugin (can be downloaded using imageJ>Help>Update>Manage Sites through selection of IBMP-CNRS site).
• Ignacio Arganda Carreras & Curtis Rueden skeletonize 3D plugin available here https://github.com/fiji/Skeletonize3D. Meiosis bar Macro was used/tested with 2.2.2 version of this plugin.

The whole macro was tested using ImageJ 1.53t, Java 1.8.0_172 and a 64-bits windows OS.

Mind spaces or fancy characters should be avoided (input folders and parents folders, file names).
