Generalized Eigenvalue De-Artifacting Instrument (GEDAI)
Authors: Tomas Ros, Yingqi Huang, Takfarinas Medani, Raymundo Cassani
This tutorial introduces the generalized eigenvalue de-artifacting instrument (GEDAI) algorithm which is an unsupervised EEG denoising method based on the leadfield filtering.
Introduction
[TODO] A description on the method
Install
Being a Brainstorm plugin, GEDAI plugin can be installed, updated and removed directly from the Brainstorm GUI. For further information, see the plugins tutorial.
From the main window go to Plugins > Artifacts > gedai > Install.

A message will appear saying, "Plugin gedai is not installed on your computer. Download the latest version of GEDAI now?" click 'Yes'.
- The plugin will be downloaded and installed automatically. Once installed, you will see a confirmation message.

By following these steps, you will successfully install the bst-neuromaps plugin.
Using GEDAI
[TODO] Expanding these points
On GEDAI provided data
- Create a new protocol
- Importing data
- Install GEDAI plugin
- Running GEDAI process Description of the process GUI and each of their elements
- Results
On epilepsy EEG
- We can use GEDAI on the raw EEG data in the Epilepsy tutorial
