Dear Peng,
The messages you got do not indicate a problem. However, it is indeed
true that you have no fiducials because fiducials are not available in
Fieldtrip data structure. You can go to 'Toolbox/MEEGTools/Copy MEG
sensors' to re-read sensors and fiducials from the original dataset.
Alternatively, you can look at
man/example_scripts/spm_ft_multimodal_preprocessing.m , particularly
line 70 to see how to integrate reading fiducials in your script.
Best,
Vladimir
