[Eeglablist] problem with source localization in different wave

[Louis Renoult]

Hello,
Dipfit performs equivalent dipole source localization of independent components. To localize a difference wave, you will need to first decompose the relevant experimental conditions with ICA. Then you can use the envtopo() function or its Study version (std_envtopo), to identify the independent components (ICs) that contribute the most to your difference wave. From the GUI: Plot/Component ERPs/With comp. maps (compare). If you use the Study mode, you can refer to the help section "Modeling condition ERP differences using std_envtopo()" at http://sccn.ucsd.edu/wiki/Chapter_04:_Independent_Component_Clustering
The ICs that make the greatest contribution to your difference wave can then be localized with Dipfit.

Good luck,
Louis

Dear lists:
I want to locate dipole using dipfit, however, I don not know how to locate different wave
I was wondering  is any one could help me,
or it is  not necessary to locate the different wave, if it is the case,would any one please send me some published paper on it ?
Any help will be appreciated!
 Best wishes!

                                                                                                    Sincerely yours:yunzhe liu
