Ctrax is an open-source, freely available, machine vision program for estimating the positions and orientations of many walking flies, maintaining their individual identities over long periods of time. It was designed to allow high-throughput, quantitative analysis of behavior in freely moving flies.
Please see the following tutorial availabe in this package and its algorithms are described in detail in the article "High-Throughput Ethomics in Large Groups of Drosophila," Branson et al., Nature Methods, 2009 (DOI:10.1038/nmeth.1328).
