The relative root mean-square error (RRMSE, given by Eq. 25) histograms for all cells and for six protocols (A–F) at 37°C. Markers indicate the best (∗), median (‡), and 90th percentile (#) RRMSE values. The raw traces with the best, median, and 90th percentile RRMSE values, for both the model (red) and data (blue), are shown in the panels above, together with the voltage protocol shown on top. Note that the currents are shown on different y axis limits to reveal the details of the traces. The same analysis is presented for the remaining protocols in Fig. S16.
