Table 10. EEG/ERP Data Preprocessing

Term	URI (NEMO)	Definition
Digital filter transformation	NEMO_7669000	Offline removal of signal above or below a certain frequency level
Data cleaning transformation	NEMO_4273000	Offline removal of any signal that is not of interest to the researcher
ERP event (for averaging)	NEMO_6783000	The role ofan event (e.g., stimulus onset)that is used forEEG averaging
ERP epoch length	NEMO_3620000	The durationof an ERP, where the time of the event is designated as time zero.
ERP baseline length	NEMO_6232000	The durationof ERP baseline (by default, the end of the baseline is the onset of the ERP)
Offline reference	NEMO_0000321	Offline schema used for re-reference

¹ An alternative to the use of a controlled vocabulary is to discover mappings between data annotations [19,20]. However, this process is nontrivial, and its success depends on the nature and amount of variability in the data.
