Each individual .csv file provides the raw data for a figure in the manuscript "Cells under stress: An inertial-shear microfluidic determination of cell behaviour". 
The names correspond to the main figure text (e.g. Figure1.csv) or a figure from the supporting information (e.g. supporting_figure_1.csv).
Any additional analysis such as fitting functions and extracted parameters are describedd within the bulk of the paper or the supporting information.
