Abstract

Analysis of behaviors of model organisms has a number of applications, particularly to determination of the function of genes and neurons. Drosophila larva is an especially convenient model system for this kind of study because of availability of powerful genetic analysis tools and of automated tracking software that allows high-throughput recording of animal’s shape and position characteristics as time-dependent signals. We have developed an open source software that allows a high-throughput detection and analysis of a comprehensive set of meaningful behaviors of this species. Using the recorded signals as input variables and a set of processing thresholds as parameters, the software employs model-based algorithms to detect the behavioral actions with high accuracy, typically 1-5%. For each detected action it extracts and stores meaningful quantitative features that allow statistical discrimination of mutants from wild type animals and set stage for subsequent application of machine learning techniques to classification of the mutants.
