<div dir="ltr"><div>Hello FieldtripList,</div><div><br></div><div>I am trying to differentiate brain areas responsible for two different conditions using the method show in the tutorial(<a href="http://fieldtrip.fcdonders.nl/tutorial/beamformer">http://fieldtrip.fcdonders.nl/tutorial/beamformer</a>), and so far I have tried to subtract condition# 1 minus the #2, and divided by the average of the baseline period (pre-stimuli presentation), i.e., (Post#1-Post#2)./(Average of Pre#1 and Pre#2). I think this division is for normalisation purposes. Is this the right normalsation? What normalization do you suggest to use? Is it necessary to normalise?</div>
<div><br></div><div>thanks</div><div>Ye </div></div>
