[FieldTrip] Possible bug in ft_databrowser...

["Jörn M. Horschig"]

Dear Marco,

As you can see on line 78, the databrowser code hasn't been changed 
since March 9 (well, actually I just comitted a change which has nothing 
to do with your error). Can you get back to me personally?

Could you then perform this command on your data:
   data = ft_checkdata(data, 'datatype', {'raw', 'comp'}, 'feedback', 
'yes', 'hastrialdef', 'yes', 'hasoffset', 'yes');
and then copy the output of
   ft_checkdata(newdata)
and send me that via mail?

The first call should add an offset field to your data-structure of size 
140x1. If that does not work, then something goes wrong in ft_checkdata, 
but I cannot see from the code what possibly might go wrong there (line 
559 ff.)
If you send the output to me, I might track down what is going wrong. 
The databrowser works fine for me and I have not heard complaints from 
others, so I am a bit worried by your problem ;)

Best,
Jörn
