ASCII to EDF format converter

The Approach The main goal of this post is to explain how to convert OpenBCI datasets in EDF format files in a simple, easy and straightforward way. Many researchers and programmers have shared their files and software, either on an individual basis or in the framework of a larger group or project. In the name…

Left-hand vs. Right-hand finger tapping experiment

The aim of Brain-Computer Interface (BCI) is to improve the autonomy of people with severe motor disabilities by new communication and control options. It is commonly known that either if you perform a movement, or you think about actually doing this movement, the same area in the brain is activated. Therefore, the point with these…

Two External Buttons on OpenBCI 32bit Board

Sometimes, when studying EEG or other biopotential signals, you will want to have precise timing between external events or stimulus and the data stream. For example, motor imagery based brain-computer interface (BCI) translates the subject’s motor intention into a control signal through real-time detection of characteristic EEG spatial distributions corresponding to motor imagination of different…

Loading OpenBCI datasets in EEGLAB

EEGLAB can be used for the analysis and visualization of EEG datasets recorded using OpenBCI hardware and software. EEGLAB can work with a variety of different file types, including those that are exported from the OpenBCI GUI, as we saw in the previous post. The Approach The main goal of this post is to explain…
