<b>Emne: </b>[FieldTrip] How to calculate relative power for source imaging<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-AU" style="font-size:11.0pt;mso-fareast-language:EN-US">I am new to fieldtrip and have been using it to analyse sleep and resting wake data.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU" style="font-size:11.0pt;mso-fareast-language:EN-US">I have managed to calculate the absolute power for source imaging and successfully projected it onto individual participant’s MRI.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU" style="font-size:11.0pt;mso-fareast-language:EN-US">I wonder if there is a way to easily calculate relative power (frequency of interest / grand total power).
