EEGLAB安装及测试 - 图文

1. 在MATLABR2015a中添加EEGLAB工具箱的问题 >>eeglab

Warning: MATLAB has disabled some advanced graphics rendering features by switching to software OpenGL. For more information, click here.

eeglab: options file is C:\\Users\\cao\\eeg_options.m Error using supergui (line 140)

supergui error: argument 'fig' must be numeric

Error in eeglab>eeg_mainfig (line 1281) supergui(gcf, geometry, [], listui{:});

Error in eeglab (line 411) javaobj = eeg_mainfig(onearg); >>

解决方案：使用MatlabR2014a及以下版本

2. 安装成功后的测试

根据《EEGLAB中文手册20120912》进行测试 (1) D:\\matlabR2014a\\toolbox\\eeglab\\sample_data File->load existing dataset

pop_loadset(): loading file D:\\matlabR2014a\\toolbox\\eeglab\\sample_data\\eeglab_data.set ... Reading float file 'D:\\matlabR2014a\\toolbox\\eeglab\\sample_data\\eeglab_data.fdt'... Creating a new ALLEEG dataset 1 Done.

pop_loadset

pop_loadset() - load an EEG dataset. If no arguments, pop up an input window. Usage:

>> EEGOUT = pop_loadset; % pop up window to input arguments >> EEGOUT = pop_loadset( 'key1', 'val1', 'key2', 'val2', ...);

>> EEGOUT = pop_loadset( filename, filepath); % old calling format Optional inputs:

'filename' - [string] dataset filename. Default pops up a graphical interface to browse for a data file.

'filepath' - [string] dataset filepath. Default is current folder. 'loadmode' - ['all', 'info', integer] 'all' -> load the data and the dataset structure. 'info' -> load only the dataset structure but not the actual data. [integer] -> load only a specific channel. This is efficient when data is stored in a separate '.dat' file in which individual channels may be loaded independently of each other. {default: 'all'} 'eeg' - [EEG structure] reload current dataset Note:

Multiple filenames and filepaths may be specified. If more than one, the output EEG variable will be an array of EEG structures. Output

EEGOUT - EEG dataset structure or array of structures

(3) ERP

事件相关电位（ERP，event-related potential）是一种特殊的脑诱发电位，通过有意地赋予刺激以特殊的心理意义，利用多个或多样的刺激所引起的脑的电位。它反映了认知过程中大脑的神经电生理的变化，也被称为认知电位，也就是指当人们对某课题进行认知加工时，从头颅表面记录到的脑电位。
