 % where the input data is a structure as obtained from FT_PREPROCESSING.

 % The configuration structure has the following options
 %   cfg.channel        = selected channel for processing, see FT_CHANNELSELECTION

-% After using this function you can call ft_artifact_threshold to get the onset and
-% offset of the large amplitude and sharp transient EDA “events".
+% After using this function you can use FT_REDEFINETRIAL and T_TIMELOCKANLAYSIS to
+% investigate electrodermal responses (EDRs) to stimulation. You can use
+% FT_ARTIFACT_THRESHOLD to determine the timing and frequency of nonspecific EDRs.
