AcqKnowledge 3.9.1 and higher for the Mac, as well as AcqKnowledge 4.0 and higher for Windows, includes a fully automated scoring system for EDA/GSR data. The feature includes options for deriving phasic EDA from tonic EDA, locating skin conductance responses, and event-related EDA analysis. In the SCR location mode, the software marks the event onset, SCR point of max response, and waveform end. The waveform onset and waveform end markers identify when the threshold was crossed. Preferences for the software allow the user to select:
