[Eeglablist] group analysis for ERP amplitude and latency

[Andrew Hill]

Hi Min,

I've done this kind of work - I suggest you explore both ERPLab (www.erpinfo.org) and the Mass Univariate ERP Toolbox.   http://openwetware.org/wiki/Mass_Univariate_ERP_Toolbox

ERPLab has a great measurement tool that will output measures of components you define (in time, relative peak, etc) and the MUT has a great multiple t-test for points along the waveform.

Let me know if you need more pointers or run into problems.

Best,
Andrew

I already got the ERP figure for each blocks and also got the average of ERP under these 2 conditions. Next, I want to do something like T-test to see if there was a statistic difference of
