[Eeglablist] Retrieve analyzed raw data

[WILLY-PAUL WESTPHAL]

I've tried to see on the web how to extract data from graphs in Matlab, but it is not helpful. It does not seems to apply to the cross-coherence graph (it is mainly for 2D graphs), Matlab returns a "Text" object type for this graph, and I cannot access to raw data, only organizational properties of the graph (fonts, size...). 
For the second alternative I don't know how to to that, I do not handle Matlab.

Access the figure and grab the plotted data from there for your uses. Search google for how to access figure data/children. 
Harder alternative though better, compute the actual data and have it in a matrix before (or without) plotting.

Hello 

I would like to know if it is possible to obtain the raw data used in building cross-coherence graphs (amplitude and phase). 

Precisely, I have plot a channel cross-coherence with both coherence amplitude and phase. But I now need the raw data, in order to measure for examples the value of the maximum coherence in the 20Hz band, or to determine under which frequency band the coherence is maximal... I so would like data in form of tables to apply searching criteria and perform statistics. 

I didn't find the way to proceed to the recovery of the data the way I want in EEGlab tutorial nor in help mailing list / forums. 

Would you give me some clues about how to do it, with EEGlab or Matlab ? 

Best regards
