What it does: Detect is a toolbox that allows users to quickly train a classifier based on multiple signal classes (usually artifacts). Detect then applies the classifier to unlabeled data. Detect has visualization tools that allow users to scroll through the data and adjust boundaries of identified artifacts. The resulting labeled data can be used to quickly perform manual artifact identification or to check results from automated methods.

Why is this important? The form of EEG artifacts varies dramatically across recordings. Detect allows researchers to manually label artifacts in part of a signal and then to apply the results to continuous detection in the remainder of the signal.
