P300 speller acquisition
Posted: Wed Sep 13, 2017 1:24 pm
Hi everybody,
I am a beginner in Openvibe and want to know how p300 speller paradigm works. I connected acquisition server using Generic Oscillator Driver and I got the underlying signal
Then when I want to run the acquisition part
,
it gives an error and warning as follows:
[ ERROR ] At time 0.086 sec <Box algorithm::(0x0000356c, 0x00004381) aka Generic stream writer> Could not open file [C:/Program Files (x86)/openvibe/share/openvibe/scenarios/bci-examples/p300-speller/signals/p300-train-[2017.09.13-15.46.33].ov] for writing
[WARNING] Box algorithm <Generic stream writer> has been deactivated because process () function returned error
What is the problem?
Should I configure the scenarios?
