\textbf{Pumping detection at low resolution (4x)}. All panels correspond to 20 min recordings in the presence of \textit{E. coli} OP50 at $OD_{600}=3$. Automated and visual inspection detection methods were compared. (A) A cumulative count of pumps as a function of time. Automated and visual inspection detection are plotted as red and blue lines, respectively. (B) The total number of pumps in 30 second windows (C) Distribution of instantaneous pumping rates (intervals between pumps). (Automatic: red, visual: blue ) . Inset: Correlation between the automatically detected and manually detected pump events. The dashed line denotes unity. Intensity corresponds to the density of pumping events. (D) Comparison of the mean rates from 5 animals, analyzed by automatic tracking or visual inspection. Pumping events were detected and the instantaneous pumping rates (intervals between pumps) were smoothed with a median-filter of width 15.  The dashed line denotes unity, the ellipsoids represent the standard deviation for each axis. To obtain a range of mean rates, 5 animals at bacterial concentrations ranging from $OD_{600}=3$ to $OD_{600}=5$ were counted to about 500 pumping events. \label{fig:longtimeseries}
