Example app and code for visualization of videos, observational data and/oraccelerometer recordings

Abstract

This is an app in MATLAB designed as an example for the publication "High-resolution ethograms, accelerometer recordings, and behavioral time series of Japanese quail" (Simian et al, 2023; Sci Data) to show simultaneously video recordings and data obtained from accelerometers position on animals. It show data from the dataset simultaneously with the videofile. (https://figshare.com/s/476ff867461aeab95cce and https://figshare.com/s/d9a7f238258f66bb5c6e, respectively).

In the first two rows, users first specify the location and select the correct files to load the .csv file containing the acceleration data obtained from the accelerometer and the video files. In the third row users select the fragment of time in which he acceleration vector will be plotted and the synchronization parameter (t0Acc in Table 8). By pressing plot, three axes of acceleration data are displayed (i.e. ax, ay and az, black lines on plots). The zoom interval (bottom right) allows users to zoom in on a specific fragment of the acceleration data of interest, and then by pressing the play button users can observer the corresponding video fragment. Transparent vertical blue bars show the temporal reference between three axes of acceleration data and the progress of the video recording. The screen capture shows the exact time in which reproductive behavior was being performed (note the male mounted on female in right hand image).
