Jinx is a free and easy to use tool for the segmentation of 3D data sets. Jinx was designed specifically for 3D electron microscopic data sets produced using electron tomography, but may be used for any aligned 3d data set.
Jinx contains the facility for annotating 3D microscopic data using formal ontologies.
The current version of Jinx allows the choice of ontologies, including the Neuroscience Information Framework (NIF) ontologies, which includes an extensive ontology for subcellular anatomy of the nervous system based on our Subcellular Anatomy Ontology (SAO).
