<br>
it should work like this:<br>
<br>
<i><small>cfg = [];<br>
cfg.layout = 'XXX.lay';<br>
cfg.xlim = [18 22];<br>
cfg.zlim = 'maxabs';<br>
figure;<br>
ft_topoplotER(cfg, fft1);</small></i><br>
<br>
Note that <i>cfg.xlim </i>needs to be a vector with two
elements.<br>

<pre wrap="">Dear all,
Is it possible to use ft_topoplotER to draw selected frequency peaks
over scalp after FFT analysis?
I did frequency analysis of EEG signal in the range 3-42 Hz with the
following settings:
cfg = [];
cfg.output = 'pow';
cfg.channel = 'all';
cfg.method = 'mtmfft';
cfg.taper = 'hanning';
cfg.trials = 'all';
cfg.keeptrials = 'no';
cfg.foilim = [3 42];
fft1 = ft_freqanalysis(cfg, avg1);
I would like to draw a scalp distribution of FFT peaks for, say 20 Hz.
(I've got _only_ frequency domain data).
Is it possible to do it with with the ft_topoplotER function? What
settings are needed?
I tried it using cfg.ylim nor cfg.xlim parameters but they do not seem
to be related to the parameter (the frequency selection) I try to
manipulate.
Any help will be greatly appreciated!
Best,
Marek
