= SEEG epileptogencity maps =
''Authors: Francois Tadel, Olivier David.''

This tutorial introduces some concepts that are specific to the management of SEEG recordings in the Brainstorm environment, and explains how to compute maps of epileptogenicity from ictal recordings. It is based on a clinical case from the Grenoble University Hospital, France.

Note that the operations used here are not detailed, the goal of this  tutorial is not to introduce Brainstorm to new users. For in-depth  explanations of the interface and theoretical foundations, please refer  to the [[http://neuroimage.usc.edu/brainstorm/Tutorials#Get_started|introduction tutorials]].
