Extracting data from singleplot TFR

[Ingrid Nieuwenhuis]

Dear Piers

singleplotTFR uses imagesc to do the plotting. Before that it selects the
appropriate 2D (time-frequency) tile from the data. I'm not familiar with
hgsave, but singleplotTFR is not a complicated function, so I'd advise you
to look into the code and you can probably easily get access to the values
by debugging. More info on the FieldTrip plotting functions can be found on
documentation > tutorial > plotting:

Hope this helps,
Ingrid

Subject: [FIELDTRIP] Extracting data from singleplot TFR

Dear all,

I would like to get access to the values produced by singleplotTFR that go
into the contour plots.

Normally, I understand that a sequence like this:

h = plot(y,x)
hgsave(h,'plot_fig.fig')
a = load('plot_fig.fig','-mat')

should allow one to access the datastructure in a plot.

However, when I tried hgsave with singleplotTFR I got the following error
message:

??? Error using ==> hgsave
Invalid handle

Please can you advise how I get to the data.

Thanks

Piers C
