Dear Phillip,

Thank you for your reply,
Is there any example in mne for this (modifying channel)? most of the
example in mne started with load fif file that I do not have,
I do not understand how to modify or build meg sensors,  can you give me a
real example please?
if I want to export the channel file from brainstorm (.pos) and is there a
way to load it in mne to use the analysis of mne tool?

Thank you
