egi2besa2fieldtrip - topoplot layout

[Virginie van Wassenhove]

Hi Fieldtripers,

below find the relevant sample code I am using to plot cluster
results with Fieldtrip release v. 20070514 (latest?).

I have read previous posts in the discussion but I still bump into
this issue (not sure how old the discussions were).
The recordings were made with an egi system and preprocessed in besa.
Although I am using the prepare_layout function, the layout in
topoplotER (and other plotting tools) needs to be rotated by
90degrees clockwise.
I have tried to use cfg.rotate (in the for loop below, commented
here) but that does not change anything.

Do you have any suggestions on how to overcome this problem?
Thanks in advance for your help!

Virginie
