Table 2. SC signal’s features, available at.SC.features.

Variable (Labels used in exported files)	Description
Event data
Event.nr	Sequence number of event/marker
Event.nid	Numerical ID of event
event.name	Optional name or description of event
Event.ud	Optional user data associated with event
Continuous Decomposition Analysis (CDA) (Extraction of Continuous Phasic/Tonic Activity based on Standard Deconvolution)
CDA.nSCR	Number of significanta SCRs (Skin Conductance Responses)
CDA.Latency	Response latency of first significanta SCR within response window b[s].
CDA.AmpSum	Sum of significanta SCR-amplitudes of SCRs within response windowb. (reconvolved from corresponding phasic driver-peaks) [μS]
CDA.SCR	Average phasic driver within response windowb. This score represents phasic activity within response windowb most accurately, but does not fall back on classic SCR amplitudes [μS]
CDA.ISCR	Area (i.e. time integral) of phasic driver within response window. It equals SCR multiplied by size of response window b[μSbs]
CDA.PhasicMax	Maximum value of phasic activity within response windowb [μS]
CDA.Tonic	Mean tonic activity within response windowb (of decomposed tonic component)
Standard trough-to-peak (TTP) or min-max analysis
TTP.nSCR	Number of significanta SCRs, within response windowb
TTP.AmpSum	Sum of SCR-amplitudes of significanta SCRs within response windowb [μS]
TTP.Latency	Response latency of first significanta SCR within response windowb [s]
Global Measures
Global.Mean	Mean SC value within response windowb (within response window)
Global.MaxDeflection	Maximum positive deflection within response windowb

^asignificant=which amplitude surpasses the threshold of 0.01 μS⁴¹

^bwithin response window=the response window considered for each stimulus was different, and was equal to the whole duration of the stimulus, plus additional 300 ms to account for the relatively slow dynamics of SC response.
