The purpose of the preprocessing stage is to remove artifacts or unwanted segments from the data, as well as apply a filter. To begin preprocessing, click the "truncate” icon in the "Data Processing" Box. This option will open a window which allows you to remove specific sections of the data as you see fit. This can be done by selecting the portion of the data you wish to remove (either by mouse or entering the time points) and clicking “cut”. Once finished, click “save and close”.
The “Remove discontinuities” option allows for discontinuities in the data set (e.g. periods of empty data resulting from removing sections via truncating) to be removed this is done by clicking the “remove” option. The use of these options is determined by how the data collection process went and may not always be needed.
