[FieldTrip] Where can I get 4D layout for MEG result?

Tue Jan 31 21:27:44 CET 2012

Dear Duo

I am not sure whether it is a problem with the FieldTrip code or with your particular computer and dataset. I suggest that you report it on http://bugzilla.fcdonders.nl and that you make the cfg and the comp data structure available. One of us in Nijmegen can then check whether the problem can be reproduced. In reporting it on bugzilla, please include details on your MATLAB and operating system version. We've had problems in the past where MATLAB was not fully compatible with specific language settings when reading text files.
