Openvibe gets data from the acquisition device (e.g., Biosemi) through the Acquisition Server and sends it to one or more clients (e.g., OpenViBE designer). Clients can be in a different machine on the same network.
## Our experiment
Based on the documentation from R. Becker:
#### Preparation before experiment
- Create a folder for current measurement (e.g., Measurement_666) with two subfolders:
- Acquisition material". Contains copies of:
- All audio stimuli and .xlsx file referring to them (for PsychoPy)
- Inpout32.h, inpoutx64.lib and inpoutx64.dll. These are necessary for the EEG markers
- Openvibe experiment file 'alpha_triggered.xml' file (output will write individual mean & sd alpha ratios) "Output data" .
## OpenViBE designer 64bit
### Input settings
Open the openViBE experiment .xml file ('alpha_triggered.xml') and set the path and file name of the output files in the boxes showed in the figure:
