OpenViBE implements a drift correction process to allow devices without hardware triggers to reliably tag signals during acquisition. The other two channels are the 2 Auxiliary channels. Atlantis devices use two electrodes per EEG channel. In order to activate this feature, edit your configuration file and point the appropriate variable to the file you want to dump the stream in. These devices have been supported by OpenViBE since version 0. Note that each use of the acquisition server will overwrite the previous dump.

Download this documentation as a PDF file. Brainmaster software device serial number can be found on a sticker on the back of your device. OpenViBE implements a drift correction process to allow devices without hardware triggers to reliably tag signals during acquisition.
Check that your serial number is set correctly Check that your passkey is set brainmsater Check that you use the passkey you brainmaster software from Brainmaster for OpenViBE and that you are not using the passkey that should be used for Brainmaster Try with a lower Bds rate.
It is not recommended brainmasrer disable the drift correction brainmaster software. Then run the acquisition server. Its format is as follows: In order to reduce the buffer size and latency of the COM port, process as follows:. During the buffering period, OpenViBE believes the device does not send enough samples and adjusts the drift accordingly.
This results in four channels: The device passkey should be requested to Brainmaster support. Note that each use of the acquisition server will overwrite the previous dump. Indeed the default settings cause the OS to buffer the data in big blocks.
They also include options related to the specific Brainmaster devices. The raw content of the data stream can be dumped in a text file. Entering the configuration panel of the driver offers a number of options.
In order not to set-up the keys each time you start brainmater acquisition server, you can set the following environment variables to your OpenViBE configuration file:. Hosted by powered by WordPress.
The driver supports brainmasfer following models:. Still hardware filter usually have better performances than software filters. This document was written by Mensia Brainmaster software However, if you still want to disable it, process as follows:. Then run several tests brainmaster software the acquisition server and save the openvibe-acquisition-server.
This issue can be solved reducing the buffer size and latency of the COM port which the device is connected on. These devices have been supported by OpenViBE since version 0. So for that reason and as an softdare, you can change these settings manually and go ahead sofware a brainmaster software signal.
Atlantis devices use two electrodes per Sftware channel. These options include the common options that you find in all OpenViBE drivers subject identifier, subject age and subject gender.
In order to activate this feature, edit your configuration file and point the appropriate variable to the file you want to dump the stream in. The COM port can be autodected. The other four channels are the 4 Auxiliary channels.
As soon as a -big- brainmaster software of samples gets to OpenViBE, it realizes too many samples were acquired as it adjusted the drift previously so it -again- adjusts the drift in the opposite way, causing the signal to be significantly modified this is the worst scenario happening for the drift correction process!
It happens that some ports can be brainmaster software even if no Brainmaster device is plugged to them for instance modem and bluetooth devices usually use COM ports as well. It is a different key than the one you have for Brainmaster software. The other two channels are sofware 2 Auxiliary channels.
