Hi Zhang,
You could add a field to an existing structure variable produced by either
ft_timelockanalysis or freqanalysis. Let's say you call it "real". This
field should has to contain at least a 2d matrix with the order
channel_time. You could also make a dummy variable that looks like this.
When calling ft_topoplotER or ft_topoplotTFR you should then use cfg.zparam
= 'real'.
Alternatively you can replace the data in the .pospctrm (for freq data) or
.avg field ( for timelockdata ) with your data and use the default
cfg.zparam when calling the plotting function.
Hope this helps!
