Dear SPMers,
I encountered an error message in SPM8b when trying to compute a Grand
average ERP over 4 subjects:
>> Ok: All data files have the same dimensions.
??? Error using ==> plus
Number of array dimensions must match for binary array op.
Error in ==> spm_eeg_grandmean at 259
d(j, :) = d(j, :) + D{k}(j, :, ind);
Error in ==> spm at 876
evalin('base',CBs{v-1})
??? Error using ==> spm('PopUpCB',gcbo)
Error using ==> plus
Number of array dimensions must match for binary array op.
??? Error while evaluating uicontrol Callback
All m*.mat files have the same number of conditions and the labels match.
Does anyone have an idea what could have gone wrong?
Thanks in advance,
Johannes
