# Introduction

The TMS-EEG signal analyser (TESA) is an open source extension for EEGLAB that includes functions necessary for cleaning and analysing TMS-EEG data. This user manual provides a brief overview of how to clean and analyse TMS-EEG data using TESA functions.

TESA is a community led project with the aim of making state-of-the-art cleaning and analysis methods available to TMS-EEG researchers. TESA does not advocate for one specific pipeline or analysis technique, but instead makes as many options available as possible, thereby enabling comparisons of different methods.
