Hello all, I cannot import my eeg data in spm. The data are in .mat format (channelsXtime). I have tried to put the data in a Fieldtrip raw data struct according to chapter 13.2 of the spm8 manual (inside man folder) but when I convert the struct in spm I take the following errors: Warning SOPEN: Automated OVERFLOWDETECTION not supported - check yourself for saturation artifacts. ??? Reference to non-existent field 'SPR'. Error in ==> read_biosig_header at 60 if length(biosig.SPR)>1 & any(diff(biosig.SPR)) Error in ==> read_header at 1083 hdr = read_biosig_header(filename); Error in ==> fileio_read_header at 11 [varargout{1:nargout}] = funhandle(varargin{:}); Error in ==> spm_eeg_convert at 70 hdr = fileio_read_header(S.dataset, 'fallback', 'biosig'); Error in ==> spm_eeg_convert_ui at 79 D = spm_eeg_convert(S); ??? Error while evaluating uicontrol Callback Moreover, I take the same mistakes when converting the mafdeMspm8_example.mat that I downloaded from the SPM website. Can someone advise of a way to import the data in spm?
