Based on Electroencephalogram (EEG), neuroimaging technologies and network analysis approaches are widely used to discover the brain's secret. Also it has many a time been regarded an important role for development of the brain-computer interaction that is used on intelligent robots, unmanned aerial vehicles, brain communications in the future. Most studies have showed that the interactions among different brain areas contribute to the ability of the brain in processing the corresponding information, while the diseases are also reported to be closely related to the connections among the whole brain structures. Until now, many EEG analysis software still lack the systematic brain network analysis function. Based on MATLAB platform, we achieve the graphical user interface system of EEG Network Analysis (ENA) that mainly includs the following aspects: 1. The improvement and innovation of brain electrical data analysis and processing algorithm; 2. The system supports batch processing data and several mainstream data loading and display, according to the diversity of EEG data format; 3. Preproccessing; 4. Using Welch, PCA, RobustICA, MNS methods to analyze the characteristics of EEG from time domain, frequency domain and spatial distribution; and 5. Brain network analysis including the undirected weighted network and directed network.

More details about the (ENA) system can be seen in our original paper, and it may be a promising technique for exploring various EEG data.
