[Eeglablist] export individual ERP data from study files

[A T]

Hi there!

I need to export individual ERP data from the .daterp study files. I found
a plugin that seems to do just that:

zpf.psychologia.uj.edu.pl/mwexport

But I haven't been able to run it in my data. I get the following error:

Index exceeds matrix dimensions.

Error in export_mw_ele (line 58)
var2dim = size(STUDY.design(1,STUDY.currentdesign).variable(1,2).value,2);
 %number of levels for var2

Error in pop_mwexpgui>bt_export_Callback (line 157)
            export_mw_ele('erp', winlohi(1), winlohi(2), mintrials,
expfilename, grplabelson, varsuffix, STUDYGLOBALMW);

Error in gui_mainfcn (line 95)
        feval(varargin{:});

Error in pop_mwexpgui (line 43)
    gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)pop_mwexpgui('bt_export_Callback',hObject,eventdata,guidata(hObject))


Error while evaluating UIControl Callback


I also found the following syntax in a previous question:

*[STUDY erpdata] = std_erpplot(STUDY,ALLEEG, 'topotime',[300 400] ,*

>* 'channels',{'FP1' 'FP2' 'P7' 'P8' 'F7' 'F3' 'Fz' 'F4' 'F8' 'FCz' 'T7' 'C3'
*>* 'Cz' 'C4' 'T8' 'P3' 'Pz' 'P4' 'O1' 'O2' 'Oz'});
*>>* csvwrite('erp1.csv',squeeze(erpdata{1}));
*>* csvwrite('erp2.csv',squeeze(erpdata{2}));
*>* csvwrite('erp3.csv',squeeze(erpdata{3}));
*>* csvwrite('erp4.csv',squeeze(erpdata{4}));*

But need to export participant numbers and channels names as well.

Does anyone know of a way to do it, or an updated version of the plugin?

Thank you so much for your kind attention!
