Raw Data_Noise reduction
Mechanical interaction was measured by monitoring fluorescent beads embedded in the substrate and performing digital image correlation analysis to obtain the displacement field and the strain field generated by a beating cardiac cell. We are happy to provide the original time lapse movies, however, the movie size for a single cell experiment is at least 10GB (The size of a time lapse of a cell interacting with a probe is 2GB and we use at least 5 interaction parameters). For the experiments of mechanical interaction between mechanically-coupled cardiac cells, each measurement is a 2GB time lapse movie. Our data consists of n=34 cells in the mechanical-probe assay and additional n=30 cells in the mechanically-coupled cardiac cell assay.
