EDR3: Elements Data Reader V3

The EDR3 software interface enables an easy control of all the eONE, multichannel amplifiers and nanopore readers, showing and saving data in real time. Input current ranges, bandwidth, voltage stimuli and electrode offset compensation can all be easily selected and modified. Data can be stored in commonly used formats like .dat or .abf. Resistance, Capacitance and rms noise can be continuously monitored. EDR3 is currently available for Windows and OS X and it is always included in the instrument price.

On the main window you can find:

  • the Controls tab, to set the current range (the gain), the sampling rate, the digital filters;
  • the Voltage Protocols tab, to apply the required voltage stimulus using a set of different parametric voltage protocols, like pulses and ramps of various duration and amplitude;
  • the Current display window, which shows the actual current measured;
  • the Voltage display window, which shows the voltage stimulus applied;
  • the Analysis tab, featuring a set of analysis on the data like R and C estimation, rms noise measure, current histograms, event detection, FFT and I/V graph;
  • Labbook tab, to write notes and experimental data linked to the current traces;

A set of shortcuts is available for fast control via keyboard:

Online analysis module

The online analysis enhances the EDR3 features. A variety of analysis can be done on live experiments, such as current histograms, Dwell and inter-event time histograms, I/V graph, FFT. The following videos showcase the available online analysis. More information is available in the corresponding guide.
