<P><FONT SIZE=2>Dear Fieldtrip experts,<BR>
<BR>
I am using EEGLAB to do artifact rejection with ICA.<BR>
<BR>
I export the file to fieldtrip with eeglab2fieldtrip,<BR>
but I had to make some changes to be able to compute the planar transformation<BR>
that you might want to include by default in the function:<BR>
- transform to single trial<BR>
- add the .grad<BR>
- change data.label to column<BR>
- change data.trial to double<BR>
<BR>
Best regards,<BR>
