			<Text>The preprocessing of the signal is
performed here...

&lt;u&gt;&lt;b&gt;Note:&lt;/b&gt;&lt;/u&gt; be sure that the
&lt;i&gt;sampling rate&lt;/i&gt; and &lt;i&gt;sample count
per buffer&lt;/i&gt; you use in the &lt;u&gt;acquisition
server&lt;/u&gt; are compatible with the actual
&lt;i&gt;signal decimation factor&lt;/i&gt;</Text>

			<Text>&lt;u&gt;&lt;b&gt;&lt;big&gt;Overview&lt;/big&gt;&lt;/b&gt;&lt;/u&gt;

This scenario should be used to train
the LDA classifier.

Just configure the &lt;i&gt;Generic Stream Reader&lt;/i&gt;
box to point to the last file you recorded with
scenario &lt;i&gt;1-acquisition&lt;/i&gt; and fast forward
this scenario.

At the end of the training, you will have an estimation
of the classifier performance printed in the console.
If this performance is lower than 70%, just run a new
&lt;i&gt;4-online&lt;/i&gt; session to have better results.

&lt;u&gt;&lt;b&gt;Note:&lt;/b&gt;&lt;/u&gt; in order to run this scenario,
the spatial filter should have been trained using
&lt;i&gt;2-train-xDAWN&lt;/i&gt; !</Text>
