[Eeglablist] DIPFIT

[Tarik S Bel-Bahar]

Hello Boris, yes it sounds like you want to have a "dipole" "center"
for all the dipoles from different ICs and subjects that are
clustered together using the STUDY tools.To start, try a full
review/practice of the eeglab tutorial on STUDY level methods if you
haven't had a chance to yet.

Each IC has a dipole (or two), each subject has multiple ICs, and when
clustering is done in STUDY level of eeglab, then one can find
centroids for the cloud of dipoles for a particular IC cluster.  This
is done relatively easily, at least the basic version. Download and
use the eeglab STUDY tutorial data, and see how the clustering and
dipoles look there first.
Further, you can examine the matlab variables and EEG structure and
STUDY structure when doing so those STUDY IC+dipole clustering steps.

Check out the EEGlab online summer school videos for more about
dipfit, dipoles, and study.
Check out several recent eeglab articles using dipifit (search eeglab
+ dipfit in google scholar), you'll find articles like the following.
Also, google "eeglablist + your topic" for past instances of responses
about this topic on eeglablist.
Below are just a few examples, you can easily find them on google
scholar. Please allow me to suggest contacting Knyazev.
