Hi Everybody,

I'm trying to read a ctf, which was collected at the VUMC MEG center in
Amsterdam, using fieldtrip. I've tried tried reading the data with as
well as without Darren Weber's ctf code. Anyways, I'm following the
fieldtrip example code pretty closely (see below) and both attempts have
resulted in the error messages attached below stating that a function or
variable named coil2_pos is missing.

Any help would be appreciated.

Cheers,
Durk

p.s.,

Since this is my first post to this list, I would like to thank
everybody involved in making this stuff work.
