Event-related brain potentials (ERPs) are usually assessed with univariate statistical tests although they are essentially multivariate objects. Brain-computer interface (BCI) applications are a notable exception to this practice. Multivariate ERP assessment can be facilitated by feature extraction methods. One such method is t-CWT, a mathematical-statistical algorithm based on the continuous wavelet transform (CWT) and Student's t-test.

A detailed description of the mathematical algorithm implemented by the t-CWT software as well as the results from the assessment of the example ERP data can be found in

The first version of t-CWT was introduced in

Bostanov V. (2004). BCI Competition 2003 – data sets Ib and IIb: feature extraction from event-related brain potentials with the continuous wavelet transform and the t-value scalogram.IEEE Trans Biomed Eng51:1057-61. BibTeX reference

If you use t-CWT in your research, please cite, either Bostanov (2015), or both Bostanov (2015) and Bostanov (2004) – whichever fits best.
