Dear Vladimir, ¡¡¡¡Your guess was right. I really couldn't do 3D sources reconstruction of that data by GUI. It reminded me ''checkmeeg: data scale missing, assigning default checkmeeg: no fiducials are defined''. Then I did preprocess steps again, and found that I couldn't obtain the fiducials automatically(when I finished Converting step). I checked the other datasets, luckily, they didn't have this problem. I guess there must be some wrongs of my original dataset (only that one), right ? ¡¡¡¡As for reconstruction batch problem, with the latest version of spm8(4029) and normal dataset, I can do reconstruction by that saved "renconstruction_batch" successfully. Thus, the problems related to reconstruction batch that I confronted previously may result from the different versions of spm8. By the way, in ''MEEG head model specification> EEG head modle'' module, must I specify the ''EEG head modle'' if I just process MEG dataset? ¡¡¡¡Thank you very much for helping me solve these tiny problems! ¡¡¡¡ ¡¡¡¡Haoran.
