Variable Interface
NeuroExplorer Application object provides access to the open files and variables contained in the
files. For example, to open a document in NeuroExplorer and get the first event variable in the
document in Matlab, you can use:
nex = actxserver('NeuroExplorer.Application');
doc = nex.OpenDocument('C:\Data\TestDataFile.nex');
event1 = doc.Event(1);
Here Event() method returns a Variable object corresponding to the first event variable in the file.
The properties and methods of the Variable object are listed below.
