This stream contains information about the experiment and subject.
- Type identifier : Experiment information (0x403488e7, 0x565d70b6)
2. EEG stream
Contains the signal information for the different channels (read from the GDF file).
- Type identifier : Signal (0x5ba36127, 0x195feae1)
3. Stimulations
Contains information about the stimulations that occurred during the experiment.
- Type identifier : Stimulations (0x6f752dd0, 0x082a321e)
Settings
1. Filename
Name of the GDF file to read.
- Type identifier : Filename (0x330306dd, 0x74a95f98)

Examples
If your GDF file is located in your /tmp directory, you can configure the plugin as follows :
Filename :
Samples per buffer :
Several example GDF files can be found in the share/openvibe/scenarios/signals/ folder.
Practical example :
Let's add a GDF file reader box to an empty scenario. One should also locate a GDF file and enter its path in the 'Filename' setting of the box. A second setting allows to specify the number of samples to be sent per data block.
This box has 3 output connectors, corresponding to experiment information, stimulations and signals. One can connect the last two to the two input connectors of a Signal Display box to visualise the signals and/or stimulations stored in the GDF file.
Miscellaneous
The experiment information output isn't operational yet.
