Hi all,
We are trying to run the demo p300 speller task from LSL source and EMOTIV 32 channels EEG. When we run the task the signals are being detected but the speller task doesn't run after the first letter. Can someone please help us in identifying the possible reasons for this?

Eg. if the word to be spelled is "The" then only T is shown and then the task doesn't go further.

There are multiple possibilities why this may happen.
1) The NumberOfSequences parameter is set to a different value than EpochsToAverage parameter.
2) You have specified the <PAUSE> command for a letter contained in your text.

For more information about the P3SpellerTask, see https://www.bci2000.org/mediawiki/index ... pellerTask.

Best regards,
Juergen

The p3temporalFilter parameters which have EpochsToAverage do not show up for LSLsource configuration attaching a screenshot for your reference. However, it does show up for signal generator . Also the problem is there when we run LSL source with EMOTIV eeg. The task runs fine with signal generator.

Hi, can you post the content of the batch file you are using?
