[FieldTrip] One or more output arguments not assigned during call to "read_16bit"

[Vitória Piai]

Hey Arjen,

Brilliant!! Thanks so much for the suggestion, it worked...
I'm still having to comment out line 356 (chanindx = 
EDF.chansel;%(chanindx);), so something is going on but at least now I 
can work with the data!

Thanks again,
Vitória
