If Matlab provides you the basic tools to develop, EEGLab is an open source package that already implements a vast range of different functionalities under Matlab that are commonly (and not so much) used while analyzing and processing EEG data: semi-automatic artifact removal, filtering, independent component analysis (ICA), time/frequency transforms, feature extraction, etc.

As usual, Octave is also suitable for a lot of the work that can be developed under Matlab, with the advantage of being open source. Many functionalities that you may need (computation of power bands on frequency domains, detection of event-related potentials, filtering of data, feature extraction, classification, etc.) can be developed using the framework of the processing toolbox.

Matlab, of course, is a powerful tool, especially with the signal processing toolbox.

There is a wide range of available software, but we want to cover here the most transversal ones that we know, in the sense that itвЂ™s software that can be used in a wide range of applications. In order to work with your data and get your results, youвЂ™ll need to analyze it to detect event-related potentials, perform a time-frequency analysis, or extract some features from the signal to be used later. Photo credits: Patrick.kramer and MrSandmanД«ut visualization is only the first step to take with your data. There are other more specific software like Tempo, вЂњan open source software for 3D visualizationвЂќ providing graphical-scalp drawing for the activation domain, or EEG-Visualisation, implementing different methodologies for EEG visualization (see the webpage and the linked scientific publication there for more details).

Bioelectromagnetism is a вЂњtoolbox has been developed to facilitate quick and easy import, visualization and measurement for ERP data.вЂќ It is specially indicated for event-related data, and is able to import/export file-formats that other software canвЂ™t (.avg.

Biosigis another large toolbox for Matlab (and Octave) that offers a vizualisation tool.

Besides being a processing data toolbox, it also provides visualization functionalities, both in signal plotting form for the time domain, or in a graphical-scalp drawing for the activation domain.

EEGLab вЂњis an interactive Matlab toolbox for processing continuous and event-related EEG (вЂ¦) dataвЂќ.

An interesting capability is that it offers the possibility to load a streaming file, so if the software bundled with your EEG package doesnвЂ™t provide any monitoring software (on-line visualization), you can use this one to monitor the signal while recording it. It also provides filtering functionalities, power on the frequency bands computation, as well as the possibility of down-sampling your signal. It offers a graphic visualization of the signal, as well as an integrated list of trigger marks present in the file.

The EDF browser supports a wide range of common EEG file-formats as input, and converts them to EDF.

If youвЂ™re experienced, you may even be able to spot some event-related potentials on your signal, or make an estimation of the power of the signal in low frequency bands (like alpha).Д«esides the proprietary applications that many commercial EEG kits bundle (like Neuroelectrics Instrument Controller, NIC, bundled with Enobio and Starstim), there are some other options of software available that you can use to visualize EEG data. This will enable you to visually inspect possible problems with your setup, identify artifacts like eye-blinks, or even identify artifacts from external devices. The first thing you may want to do once you finished recording your EEG data, or maybe even in between different recordings, is to visualize your data. This post intends to be collaborative, so do not hesitate to contribute to it through your comments! Today weвЂ™ll try to go over the different options you have, both for visualizing and for analyzing your EEG data.Дisclaimer note: This is only a brief overview covering the software we commonly use. Perfect, that sounds like a good planвЂ¦ but how? What tools should we use? EEG software Or maybe even go one step further and analyse it. What now? Well, if you have experience with EEG, youвЂ™ll probably want to visualise the data you recorded. LetвЂ™s say you followed the advices, and you already have a good EEG recorded.
