The EEGBrowser is intended to be a modern drop-in replacement for EEGLAB's eegplot
function based on MoBILAB's visualization functions.
- Download
- Uncompress
- Rename the folder as "EEGBrowser", and place it in your
eeglab/plugins
folder. - Run
eeglab
oreeglab redraw
(if you don't want to clean your current EEG structure)
Note: Although EEG Browser is based on MoBILAB, the latter is not needed for it to work.
Plot channel data (default)
pop_eegbrowser(EEG);
or
pop_eegbrowser(EEG,1);
Plot IC activations:
pop_eegbrowser(EEG,0);
To get the handle to the widget (useful for adding your own customizations):
hBrowser = pop_eegbrowser(EEG,0);
Other features:
- Use the
<<
and>>
keys to move to the next page centered around the selected event marker. - Use
-
or+
buttons to reduce or increase the scale respectively. - Click on the figure and use
-
or+
keys in your keypad to reduce or increase the scale respectively. - Use the mouse to select bad trials. See example here.
If you want to extend the capabilities of the EEG Browser follow these steps:
- Create a class inheriting from
EEGBrowser
, let's call itMyEEGBrowser
. See example below. - Then create your own
pop_myeegbrowser
or modifypop_eegbrowser
here to call your class passing in the EEG structure.
classdef MyEEGBrowser < EEGBrowser
properties
% Declare the properties that you need here for plotting.
% Properties store data that is used by the class for plotting.
end
% Constructor
function obj = MyEEGBrowser(EEG)
% Call EEGBrowser's constructor
obj@EEGBrowser(EEG);
%--
% Do your thing here. You can for instance add buttons, change default
% settings, and so on.
hButton = uicontrol('Parent', obj.figureHandle,...
'Style', 'pushbutton',...
'TooltipString','This does something',...
'Units','Normalized',...
'Callback',@onPush);
%--
end
end
% Define your callbacks
function onPush(src,evnt)
obj = src.Parent.UserData; % Retrieve your MyEEGBrowser object
% so that you can modify its properties
%--
% Implement the callback here.
%--
end
Save the code above in MyEEGBrowser.m and that's it. See this example for learning more about MATLAB classes.
