<p style="margin-bottom:0in">Dear EEG lab users,</p>
<p style="margin-bottom:0in">
</p>
<p style="margin-bottom:0in">I'm recording EEG data from a new wireless
EEG system (Cognionics 64 channels) and the equipment has a central
spine that runs from the back to the front, and also some straps that
run laterally over the subject's head. I was planning to digitize the
positions of the electrodes, but the digitization has an offset in
relation to the scalp surface due to the spine and straps. Is there
any function in EEGLAB that can account for the difference between
the digitized position and the actual scalp surface? What I was wondering is if there'd be
something like "shrinking the coordinates" to get the digitized positions
closer to the real electrode positions.</p>
