[Eeglablist] "How can I learn reasons of differences between written software and manuel dipole fitting results ?

[m. kazanç]

hello ,


I have some problems related to EEGLAB Dipole fitting operation.


My software and manuel result are totally different. In the attachement , I gave you my data and script , also I explain you manuel steps.


Can you help me please , where is the wrong point(s) ?



In manuel sections ,




             After I opened;       -  EEG = eeglab;



1- )  EEG = pop_importdata('data',data,'dataformat','array','srate',sampRate,'nbchan',size(data,1),'pnts',size(data,2),'xmin',1,'setname',subjectDir);


2 - )  EEG = pop_chanedit(EEG,'load',{fullfile(root,'sagura19_eloc.txt'), 'filetype', 'locs'});


3- )   EEG = pop_chanedit(EEG,'lookup',fullfile(root2,'plugins','dipfit2.3','standard_BEM','elec','standard_1005.elc'),'nosedir','+Y');


4 - )  EEG = pop_runica(EEG,'icatype','jader','options',{});


5- )   EEG = pop_dipfit_settings(EEG,'hdmfile', fullfile(root2,'plugins','dipfit2.3','standard_BEM','standard_vol.mat'), 'coordformat', 'MNI', 'mrifile', [root2 '\plugins\dipfit2.3\standard_BEM\standard_mri.mat'], 'chanfile', [root2 '\plugins\dipfit2.3\standard_BEM\elec\standard_1005.elc'], 'coord_transform',[0 0 0 0 0 -1.5708 1 1 1] , 'chansel',(1:numComps) );


6 - ) EEG = pop_multifit(EEG,(1:numComps),'threshold',15,'rmout','on','plotopt',{'normlen','on'});


  pop_dipplot(EEG,[1:numComps numComps] , 'rvrange',[0 15] , 'mri', fullfile(root2,'plugins','dipfit2.3','standard_BEM','standard_mri.mat'),'num','on','normlen','on');




    Note: In DIPFIT tutorial , after 5th step , pop_dipfit_settings, 3rd step is coming ; but I choose it after loading of channels. Is it really important ?

I finally ask you to learn if any problem in my code or manuel process stated above. This step is very cruical for our project due to we will model human behaviour according to active parts of the brain.
