[Eeglablist] exporting one channel from EEGLAB dataset

[James Desjardins]

Hi Ida,

If you load two data set files into EEGLab copying the following to  
the command line should give you what you are looking for (two arrays,  
one that is channel 10 of the first dataset [d1ch10], and the second  
that is channel 100 from dataset number 2 [d2ch100].


%create d1ch10 array...
d1ch10=ALLEEG(1).data(10,:,:);
%save d1ch10 to file "d1ch10.mat"...
save('d1ch10.mat','d1ch10');

%create d2ch100 array...
d2ch100=ALLEEG(2).data(100,:,:);
%save d2ch100 to file "d2ch100.mat"...
save('d2ch100.mat','d2ch100');

%clear the workspace then load saved arrays...
clear all
load('d1ch10.mat');
load('d2ch100.mat');






I hope this is helpful.
