[Eeglablist] Help with getting data from ERSP and ITC in STUDY

[Arnaud Delorme]

Dear Pavan,

that's relatively simple. After plotting your component measures, look in the history using the "eegh" command - we recently uncovered a problem preventing saving component cluster history, so you should use the EEGLAB development head (SVN version) or replace this function in your EEGLAB distribution https://sccn.ucsd.edu/svn/software/eeglab/functions/studyfunc/pop_clustedit.m. 

Then, copy the ERSP plotting command (std_erspplot) and add 4 outputs [STUDY erspdata ersptimes erspfreqs] = std_erspplot(....
Then save the data in erspdata for subsequent analysis using dlmwrite or xlswrite. See also slides 16 and 17 of this PDF.

I have done component clustering for 4 tasks (2 conditions - target, non-target for each), and have got good results for 3 clusters. I would like to get data for the ERSP and ITC for further evaluation. Can someone help me understand how to get the data please.
