Ahh, thank you very much Vladimir.

I think I know the source of your problem. Make sure that in your script you do save(D) before running the batch and D = spm_eeg_load(fullfile(D.path, D.fname)) after running the batch because the batch reads the data saved on the disk and saves the output there so the object you have in memory is not affected.

Just one more quick point to clarify for my own knowledge--where is the information from the head model stored in the dataset?
