Would anyone guide me how to redirect the output to text file for p300 speller? Like redirecting the "SPELLING IN THE RAIN(S)" to text file? Thank you.

Hi,

I'm not sure what exactly you want to do. In order to save spelled letters, you can do the following as described on the P3Speller wiki page:
http://www.bci2000.org/wiki/index.php/U ... pellerTask
1) Activate the speller's TextWindow, and use the SAVE command to save its contents into a file.
2) Set the speller's DestinationAddress parameter to a UDP port, say localhost:20321. Then, use the AppConnector example application at src/contrib/AppConnectorApplications/SimpleExample to copy data from that port into a text file: In case you actually want the speller prompt to be copied into a text file, you will need to modify the P3Speller source code. The simplest way to do this will be to add the following after line 908 of P3SpellerTask.cpp: The file's path name will be relative to the BCI2000 prog directory.
You will also need to add the following at the top of the file: Regards,
