I have created a STUDY set with three conditions and seven subjects. After precomputing channel measures, tried to plot ERPs, Spectra, ERSP and ITC. All is plotting well but ERP is giving the following error meesage:



Reading erp data...??? Index exceeds matrix dimensions.

Error in ==> std_readerp>std_readerpsub at 485
    if isfield(erpstruct, 'labels'), chanlab{k} = erpstruct.labels{k}; end;

Error in ==> std_readerp at 220
                    if strcmpi(dtype, 'erp') alldata{c, g} = std_readerpsub( ALLEEG,
                    setinds{c,g}(:), allinds{c,g}(:), opt.timerange)';

Error in ==> std_erpplot at 322
        [STUDY erpdata alltimes] = std_readerp(STUDY, ALLEEG, 'channels', opt.channels,
        'timerange', opt.timerange, ...

Error in ==> pop_chanplot at 323
                eval(a); STUDY.history =  sprintf('%s\n%s',  STUDY.history, a);
