This archive contains the dataset for the article "Motile cilia hydrodynamics: Entrainment versus synchronisation when coupling through flow". We gathered videos of cilia dynamics from different sources. For each animal/microorganism we upload the videos in different formats depending on the source: - .tiffs usually in a directory, it is composed by a series of images - .movie a format that we use in our lab and that it is combatible with our software in Matlab to tack cilium waveform - .avi For each video we also have the results from the tracking with our software. The resuts from a single video are all in a Matlab variable that has the same name but with the extension .clclk_force for example for the video "filename", the results are in "filename.clclk_force". In Matlab these can be loaded as force = load('filename.clclk_force','-mat'); For all the videos these can be directly be found in the directory cilium waveforms force files.
