Abstract: Highlights•The first published analysis of time series of single-trial N250 ERP.•Highly reproducible pipeline for precise single-trial ERP analysis.•New semi-automatic ocular artifact filtration method using ICA and EOG.•Ocular artifact removal decreased RMSE by half in the simulation study.•Ocular artifact removal improved the regression model fit by 25% ± 17%
