Dynamic clamp reading 1: CSV-file containing the raw data for the C-panel in Figure 5.
There are 22 columns, the first 11 for the voltage measurement, the next 11 for the injected current measurement. The first column indicates the time, the subsequent columns are measurements that follow each other in time.
Dynamic clamp reading 2: CSV-file containing the raw data for the D-panel in Figure 5.
The data structure is similar to the one from the previous raw data file.
Dynamic clamp summary table: Table containing the experimental datapoints that were plotted in Figure 5G.
