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
Image ,

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?

Hi,

The error says that you can't write to the path "C:/Program Files (x86)/openvibe/share/openvibe/scenarios/bci-examples/p300-speller/signals/p300-train-[2017.09.13-15.46.33].ov". This is perfectly normal, openvibe cannot write to "C:/Program Files (x86)/" without admin rights.

I would suggest that you either change this path to a folder you can write to (double click on Generic stream writer box, then change the path) or copy the scenario to your user directory. That way you'll be able to tinker with it without having to use admin rights.

Cheers !
