Hi Nicolas

The example script refers to functions that have been updated
considerably and renamed in the meantime: you should indeed use
prepare_layout function. The output contains a

lay.pos    = [X Y];
lay.width  = Width;
lay.height = Height;
lay.label  = Lbl;

You should use lay.pos instead of lay.prj.

I have updated the wiki page with the example script.

best regards,

The aim of this list is to facilitate the discussion between users of the FieldTrip  toolbox, to share experiences and to discuss new ideas for MEG and EEG analysis. See also http://listserv.surfnet.nl/archives/fieldtrip.html and http://www.ru.nl/fcdonders/fieldtrip.
