Dear Shingo,

Normally you would have all the conditions for each subject in the
same file. One slight problem is that condition labels are not
converted from EEGLAB to SPM but the order is preserved so you can
relabel your conditions after conversion either in the reviewing tool
(info/trials) paste the label list e.g. from Excel and then press
'update' and 'save'. Or you can do it in code:

D = spm_eeg_load(filename)
D = conditions(D, ':', {'label1', 'label2', ....'labelN'});
save(D);

To convert many files in a loop you could do:

files = {'file1.set', ...'fileN.set'};

for i = 1:numel(files)
   D = spm_eeg_convert(files{i});
end

or if you want to use batch you could do:

matlabbatch = {};
matlabbatch{1}.spm.meeg.convert.mode.epoched.usetrials = 1;
matlabbatch{1}.spm.meeg.convert.channels{1}.type = 'EEG';
matlabbatch{1}.spm.meeg.convert.eventpadding = 0;
matlabbatch{1}.spm.meeg.convert.blocksize = 100;
matlabbatch{1}.spm.meeg.convert.checkboundary = 1;
matlabbatch{1}.spm.meeg.convert.saveorigheader = 1;
matlabbatch{1}.spm.meeg.convert.inputformat = 'autodetect';

for i = 1:numel(files)
   matlabbatch{1}.spm.meeg.convert.dataset = files(i);
   matlabbatch{1}.spm.meeg.convert.outfile = 'outfile_name';
    spm_jobman('run', matlabbatch);
end

Best.

My EEG data files of 31 participants include 6 event markers corresponding to 3 experimental conditions (2 event markers for 1 condition). I have thus made 93 EEG data files. I could convert each EEG data file to SPM data file on Batch Editor of SPM12. However,  I cannot specify multiple EEG files on Batch Editor. I would like to avoid the manual repetitions of convert process. Can I write a batch script for conversion of multiple EEG data files? The description of m files are given below. I really appreciate any comments and suggestions. Thank you in advance.
