  530. <Text>The preprocessing of the signal is

  532. &lt;u&gt;&lt;b&gt;Note:&lt;/b&gt;&lt;/u&gt; be sure that the
  533. &lt;i&gt;sampling rate&lt;/i&gt; and &lt;i&gt;sample count
  534. per buffer&lt;/i&gt; you use in the &lt;u&gt;acquisition

  567. This scenario should be used to train
  568. the spatial filter using the xDAWN algorithm.
  569. Just configure the &lt;i&gt;Generic Stream Reader&lt;/i&gt;
  570. box to point to the last file you recorded with
  571. scenario &lt;i&gt;1-acquisition&lt;/i&gt; and fast forward
  572. this scenario.
  573. At the end of the training, you will have line in
  574. the console about eigen values.
  575. Using a &lt;i&gt;Player Controller&lt;/i&gt; the scenario will
  576. automatically pause at the end of the training.
  577. If you want details on this values, you should read
  578. &lt;u&gt;http://www.icp.inpg.fr/~rivetber/Publications/references/Rivet2009a.pdf&lt;/u&gt;</Text>
