Hi Bubble,<br><br>1. When EEGLAB performs ICA (runica.m), it first calculates the number linearly independent channels in the data (EEG.data). If every channel is independent (e.g. no electrode bridging has occurred), then there will be as many components as there are channels.<br>
<br>2. You can view the data by typing the following into MATLAB:<br>>> EEG.data(1,1,1);<br>The above code will give you the data point for channel 1, frame 1 in epoch 1.<br><br>-Keith<br>--<br>Research Aide<br>Belmonte Autism Lab<br>

Hi,<br>
<br>
I requested response to my question last week, but I didnt get reply, may be it was delivered in group so I am asking again, please help.<br>
<br>
I am doing ICA analysis in EEGLAB. I have two questions:<br>
<br>
1. How EEGlab process ICA? Are the number of channels and number of components same? why and how?<br>
<br>
2. How to check if the data are read in as either 2-byte integers or 4-byte integers properly?<br>
<br>
I got some results and they dont make sense.<br>
<br>
Thanks,<br>
Bubble<br>
<br>
