Thanks Tarik, I am thinking in the "dipole decomposition" as is proposed by Jason Palmer, I will review your proposal<br><br>Best wishes<br><br>John Ochoa<br><br><div class="gmail_quote">On Mon, Sep 17, 2012 at 9:55 PM, Tarik S Bel-Bahar <span dir="ltr"><<a href="mailto:tarikbelbahar@gmail.com" target="_blank">tarikbelbahar@gmail.com</a>></span> wrote:<br>

Dear eeglab experts,<br><br>Is possible make comparison between subjects in the ica's component space?, that is, I use one algorithm like AMICA, obtain the components and compare between subjects using the components: component number 1 in patient 1 against component 1 in patient 2, and so...<br>
