<p class="MsoNormal">Dear All,</p>
<p class="MsoNormal">I try to run beamformer analysis on the auditory MEG data (Neuromag) and have basic questions.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">1.Magnetometers and gradiometers Neuromag sensors have different scales. Does the Fieldtrip take care of this difference or should I normalize the data?<span style="">
</span><span style=""> </span>It yes, how to <span style=""> </span>normalize?</p>
<p class="MsoNormal"> </p>
<pre><span style="font-size: 12pt; font-family: Cambria;">2. I would like to do SAM analysis<span style=""> </span>of evoked field and look at the time courses at ROIs <span style=""> <br></span>(virtual channels).<span style=""> </span>The only tutorial example I have found was for the lcmv-beamformer <br>(cfg.method = 'lcmv'; http://fieldtrip.fcdonders.nl/example/lcmv-beamformer). I am not sure <br>which parameters should I specify in <span style="color: black;">ft_sourceanalysis if </span>cfg.method = 'sam'.<span style=""> </span></span></pre>
<pre><span style="font-size: 12pt; font-family: Cambria;"> </span></pre>
<pre><span style="font-size: 12pt; font-family: Cambria;">I would be most grateful for any example script of this type analysis!</span></pre>
<pre><span style="font-size: 12pt; font-family: Cambria;"> </span></pre>
<pre><span style="font-size: 12pt; font-family: Cambria;">Regards, </span></pre>
