[Fieldtrip] (no subject)

[Maarten De Vos]

Dear,

I am new to fieldtrip, and tried to get started with some basic ctf data 
(subject01.ds), but after following closely all the commando's given at 
http://fieldtrip.fcdonders.nl/getting_started/ctf, I get following 
unexpected error.  I have no clue where it comes from.

(the only thing I did differently from the manual was adding more 
fieldtrip subdirectories to the matlab path, because after running 
fieldtripdefs, matlab did not find ft_read_header)

Can anybody help me with this error?

thanks a lot,
maarten
