[Eeglablist] Extracting data from study

[Christopher Retzler]

Hi Robin

I have been using the following:

STUDY = pop_erspparams(STUDY,  'freqrange',[0 35]);
[STUDY erspdata ersptimes erspfreqs] = std_erspplot(STUDY,ALLEEG,'channels',{ 'E5','E6', 'E11', 'E12' }, 'plotsubjects', 'on' );

If you wish to also look at ITC values I believe you should use the newtimef function, but the important part is to specify the output variables you require (e.g. [STUDY erspdata ersptimes erspfreqs]). For further info see the help files for the respective functions.

Hope this helps

Chris

Subject: [Eeglablist] Extracting data from study

Hello,

I have done the precomputing and plotted the spectra to a study.
However, I am trying to figure out how to extract the individual
channel values from the figure/study so that I can perform statistical
testing on this, could someone help me with doing this? A previous
person in my lab achieved this by using:
std.changrp(128).specdata{1}), but I can't see a std variable in
matlab and my STUDY.changrp does not contain specdata.

Thanks,
