The analysis of electrodermal activity consists of first manually
editing artefacts and then second (optionally) a signal
decomposition as suggested by Benedek & Kaernbach (2010). This
decomposition extracts unsuperposed response components (a tonic
component and a phasic driver) allowing for an unbiased
quantification of SCR characteristics. Finally, the edited EDA and
the calculated signals are stored in the database.
After the EDA analysis you can export arbitrary epoch statistics
of the calculated signals, such as the area under the curve or the
maximal SCL-value of a response window, using the general value
export.
