Error with motor imagery scenario acquisition

Post by nanton »

Hello,

I'm trying to implement the Open VIBE motor imagery BCI scenarios in a research project using an Open BCI 16-channel headset. I am able to execute scenario 0 and am monitoring the signals which all seem to be running appropriately. However, I'm unable to execute scenario 1 for signal acquisition and am receiving the following error messages:
[ INF ] At time 0.000 sec <Box algorithm::(0x00000de5, 0x00006f3d) aka Graz Motor Imagery BCI Stimulator> Lua script terminated
[ ERROR ] At time 0.141 sec <Box algorithm::(0x000013d3, 0x000029d9) aka Generic stream writer> {Error description} : {Error opening file [C:/Program Files (x86)/openvibe-2.0.1/share/openvibe/scenarios/bci-examples/motor-imagery/signals/motor-imagery-1-[2018.03.29-10.12.32].ov] for writing}, {Error type} : {OpenViBE::Kernel::ErrorType::BadFileWrite (code 41)}, {Error location} : {C:\ovm\sdk\plugins\processing\file-io\src\box-algorithms\openvibe\ovpCBoxAlgorithmGenericStreamWriter.cpp::84}

I'm not sure what the error is, and would appreciate any insight on what could be preventing the execution of this scenario.

Thank you in advance,
Nick Anton
