Dear Volkmar
Thank you very much for the help.
I think I figured out how to call functions like 'sum' and 'spm_eeg_filter' and put them all in a stream line of modules.
My main mistake is too stupid to ignore that the input for "Function to be called' has to be string.
But the GUI is a little bit annoying, because when you first typed in with apostrophe and re-open it, the apostrophe disappears and if you hit 'OK', then it gives you error message.
One remaning question,
for the input, I need to give a name for val.D in the case of 'spm_eeg_filter'.
How to get the file name produced by the above module in a stream line, similar to dependency? so that I don't have to predict and write in the name by myself?
Thanks again for the help.
Sincerely,
Chou-Ching
