External Email - Use Caution
Dears:
I am wondering whether 'mne.pick_types' has a bug for CTF dataset. When I use ?gradiometer? as parameter there is no gradiometer channels were selected (mne.pick_types(raw_data.info, meg='grad?)), while the 275 gradiometer channels could be selected by using the ?magnetometer? as parameter (mne.pick_types(raw_data.info, meg=?mag?)) as shown by the screenshot. I report this information please let me know if I misunderstood anything.
My system and MNE environment is shown below:
