[FieldTrip] reading .mat in fieldtrip

[Arjen Stolk]

You could try to make one long trial, and take it from there. Load that
matrix stored in your mat file (type 'help load'), and then

data.trial{1,1} = matrix;
data.time{1,1} = 1:size(matrix,2);
data.label{1,1} = 'chan 1';
data.label{2,1} =  'chan 2';
..
data.label{8,1} =  'chan 8';

See that page, and/or type 'help ft_datatype_raw'. When your data is in raw
format, you can process it with ft_preprocessing (e.g. to filter) or
ft_redefinetrial (to create trials).

Hope that gets you on your way,
Arjen
