If you keep the Target Letter Generation box, you will be able to train the algorithms again on the recorded data.

Set the target word in the Lua Stimulator (e.g. "openvibe") and adapt the number of trials in the P300 Speller Stimulator (e.g. 8 trials for the 8 letters in "openvibe") Note: If the number of letter in the chosen word does not match the number of trial, you won't be able to train xDAWN and the classifier on the recorded data.

The Target Letter Generation box still proposes some targets in order to eventually train the spatial filter / classifier again, but you may want to disconnect that box in order to have a real free time use of the speller. The flash sequence starts automatically after 20 sec. You will then be presented a blue letter that you have to focus on, followed by a 12 times flashing sequence of the whole grid. The detected letter will be presented in green. This will be repeated 10 times. If the performance of the system does not fit your requirements, just run 2-train-xDAWN and 3-train-classifier scenarios again on the data you just recorded. note: the recorded files go to the folder where the scenario xml is located (${Player_ScenarioDirectory}/).
