<br></div><div>Yes it's possible. You have to manually specify the conditions using the following method.</div><div>After you import 3D Matlab variable, also try 'import epoch info'.

<div>Dear Makoto,</div>
<div> </div>
<div>I tried the first method and gave each category a different variable
name. Each category had three dimensions. All categories were
included in the same mat file. When I tried to import the data, EEGLAB
gave me an error. I am not sure what the menu commands are for importing
separate data files. These data are from one patient. Any
thoughts?</div>

<div dir="ltr">Dear Heracles,
<div> </div>
<div>I suggest you reshape the data from 4D to 3D (see matlab help 'reshape')
and give trials label of category. Alternatively, if you don't want to mix them
in one dataset, I suggest you separate categories such that</div>
<div>category1: channel x point x trials<br></div>
<div>category2: channel x point x trials<br></div>
<div>category3: channel x point x trials<br></div>
<div>and you'll have 3 different data sets (by the way does EEGLAB allow to
import 3D data?) However, if this 'category' is within-subject condition and
recorded at the same session (i.e. without taking off the EEG cap) I recommend
the first solution because it is better for running ICA.</div>

<div>I have an array of segmented ERP data consisting of 4 dimensions
