We recorded the steering responses of Drosophila melanogaster when presented with ventral and dorsal visual stimuli in a rigid tether virtual arena. Tethered flies were illuminated from above with an infrared light, while photodiodes below measured the shadow produced by each wing beat. Since flies steer by changing the relative amplitudes of left and right wing beats, attempts to turn produce a differential voltage by the sensor pair, and is reported as the voltage difference in wing beat amplitude, ΔWBA. This information is saved in a binary file per experiment and per fly. The data stored here has not been processed. We provide a Python code that can be used to read it, analyze it and reproduce the figures we present in our paper.
The files are compressed as a RAR file. Once unpacked they provide the file structure required by the script to read them. Feel free to contact C. Ruiz if you have any questions regarding the dataset.
The analysis is written as a Python script that can be called from the command line or imported on an interpreter such as Spyder. It is necessary to have Python installed already in the system. Follow these instructions in order to generate the plots and examine the data:
Unpack the compressed ZIP file preserving the folder structure.
Open a terminal window or an interpreter such as Spyder and run the code
The code will load the binary files, process the data and generate the plots presented in the manuscript for publication.
It will also show some lines of text at the end offering the results of the T-tests ran on the data.
