Experimental data from "Optimal cell length for exploration and exploitation in chemotactic planktonic bacteria"

This dataset is suplement to the paper:Guadayol O, Schuech R, Humphries S. Optimal cell length for exploration and exploitation in chemotactic planktonic bacteria. Under review.The dataset contains the information needed to reproduce all the experimental resuls shown in the paper , including information on the experimental conditions and bacterial tracks and cell lengths extracted from videos of populations of <i>Escherichia coli</i> swimming in the center channel of a chemotactic microfluidic device.<b>metaData.ods</b> is a spreadsheet listing the experimental times and conditions of all videos obtained, including those that were considered failed (see paper for details).<b>AW405_MGM_*_tracks.csv</b> are comma-separated-value files containing the list of bacterial tracks per each of the videos listed in metaData.ods. Data includes a track identification number spefific for each video, the mean cell length of the bacteria and the x and y positions of the centroid of the bacteria at consecutive frames. The channel of the microfluidic device is paralel to the y axis, so that the linear gradient of α-methyl-aspartate is established along the x axis. Data was retrieved from phase-contrast videos using software described in Guadayol et al 2016. Raw videos are available upon request to the authors.<br>
