<p>Hi,</p>
<p> </p>
<p>There are many discussions on ICA, but I can't find many on what happens next!</p>
<p> </p>
<p>I am now working on data where the subjects had their eyes open and looked at a computer screen.
</p>
<p> </p>
<p>I am trying to use ICA to remove eye blinks and eye movements, but it is very difficult: I have no EOC, only 7 components, and only approximately 3-5 minutes of data.</p>
<p> </p>
<p> For most subjects, it works well, but sometimes data is not well divided, of course (ex: no component has the right topoplot, or their spectrum contain alpha waves). For some subjects, I have tried many different options, but I can never really remove eyeblinks
and eye movements.</p>
<p> </p>
<p>So now if we want to compute statistics (ex, Fourier spectrum), how do I compare subjects where it worked and subjects where these artefacts were not removed!? Sometimes I feel it would be better to forget artefact rejection, so that, at least, all subjects
are more or less the same... Any idea?</p>
<p> </p>
<p> </p>
<p>Thak you very much!</p>
