[FieldTrip] Calculating ERPs with tf_timelockbaseline

[Luca Moretti]

Dear Fieldtrippers,

I have a problem concerning the calculation of ERPs with
ft_timelockbaseline. After I have preprocessed the data (re-referenced,
filtered, cleaned from artifact), this is what I have done:

inputfile = (strcat('Subject_2_clean.mat'));
load (inputfile);
layout = 'easycapM1';

%% Calculating ERP

cfg = [];
cfg.trials = find(data_clean_2.trialinfo==60);
Color_C = ft_timelockanalysis(cfg, data_clean_2);

%% Plotting

cfg = [];
cfg.baseline = [-.3 0];
cfg.channel = {'all'};
cfg.parameter = 'avg';
ERP = ft_timelockbaseline(cfg, Color_C);

figure
cfg = [];
cfg.layout = layout;
cfg.interactive = 'yes';
cfg.showoutline = 'yes';
ft_multiplotER(cfg, ERP)

%%

My problem is that it doesn't matter what kind of baseline period I am
chosing, the figure Always turn out the same for each electrode. I have
even tried to set the baseline to the Whole trial period, but the figure I
get from plotting individual channels from the multiplot is Always the same.

Can someone find something wrong with my code?

Many thanks!
Luca
