Cannot read headshape for Yokogawa recordings

If it's in MNE-Python, it can be implemented in Brainstorm as well.
I'm just not sure what is the correct way of doing this: which priority to give to which type of information, what to show in the interactive messages...
This does not seem to be a procedure documented by Yokogawa. Where are the "established procedures" you mention coming from? Are they related with only one lab?
