Introduction

This software distribution is composed of three distinct programs:

• BRAS: An image analysis program that extract the movements of the bacteria from digitised movies.
• Click & Mean: A signal analysis software which helps the interpretation of the movements extracted with BRAS.
• Video Player: A frame by frame video player.

These software have been written in Python using free software by Antoine Sirinelli for the Oxford Centre for Integrative Systems Biology. They have been used in the following publications:

• Use of a new motion analysis system to characterize the chemosensory response kinetics of Rhodobacter sphaeroides under different growth conditions, Kojadinovic M., Sirinelli A.,Wadhams G.H., and Armitage J.P., Submitted to AEM.
