Hello,
I'm new to Openvibe and I'm trying to create scenario using BCI2003 Competition files. What is the correct way to use those gdf file, and to convert them to ov files. I did that using Generic & GDF reader/writer but the scenario doesn't work.

Re: Using GDF files
Hello nsprt,
some more details would be useful, such as,
1) which files exactly? from where? if its not part of OpenViBE, whats the download link?
2) why doesn't it work?
If you think its a bug, please follow the general bug reporting guidelines,

Re: Using GDF files
Thanks for the quick reply,
The gdf file from BCI competition, dataset IIIb : Non-stationary 2-class BCI data.

The signals are displayed but I don't know why the scenario doesn't work. How openvibe interpret the stimulations of those gdf files. Are they compatible each other.

Re: Using GDF files
Hi,
I tried the gdf-reader.xml scenario included with OpenViBE on the O3VR.gdf file (the first test subject of IIIb) I downloaded from the site you mentioned. The default samples per buffer (32) in the GDF reader box causes a warning, but you can change this to 25 and the warning disappears. I couldn't see any particular problem.
What exactly is the issue? Can you be more specific?
Best,
Jussi

Re: Using GDF files
thank you jlindgren,
the display is ok, but no stimulation effecting to pass right or left when i used gdf but ov format is ok as you did in the scenario.
