Hi Theresa,

thanks for your suggestions. Let me comment on them

> - transform to single trial
That should not be neccessary. MEGPLANAR should be able to work on
preprocessed data and on timelocked data (i.e. ERFs). If I am wrong,
please let me know since it would indicate a bug.

> - add the .grad
The grad (complete gradiometer information) is not available in
EEGLAB, therefore it cannot be added in EEGLAB2FIELDTRIP

> - change data.label to column
I will ensure that that is consistently done (throughout the FT code).

> - change data.trial to double
I think that whether that is neccessary depends on the Matlab version
that you use, from version 7.0 onwards it should be possible to work
with single precision, and the conversion would not be needed. What
Matlab are you using? I can add the conversion in combination with a
check for the matlab version (i.e. convert to double if version 6,
not convert if version 7).
