Offline P300-speller-xDAWN running

Post by vicmarcag »

Hi all!

I want to run the "p300-xdawn-2-train-xDAWN.xml" scenario in an off-line way. Thus, I have downloaded the "ov-1.2.0-p300-test-data.7z" in order to use the dataset as input in the "Generic strem reader" box.

I think that it could be an easy-to-fix error, but when I run the scenario I got the following crash:

Code: Select all

<... aka xDAWN Spatial Filter Trainer> Chunk start time != chunk end time [4294975988 vs 0]
<... aka xDAWN Spatial Filter Trainer> Input signal is not continous... Can't continue
How can I fix that? How can I modify tunning xDAWN parameters?

Thanks in advance

Hi,

that scenario should always be run offline with a file, and it should work with the training file provided in that archive. Have you made any other modifications to the scenario?
