<p class="MsoNormal">Dear Fieldtrippers,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">I want to analyze data from an EEG experiment in which I split trials from one participant in two sets based on some response criterion.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I want to know how (absolute) phase at a particular point in time (say t=0) is distributed within each set of trials, and whether there is (on average) a difference in absolute phase between the two sets of trials.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I have found a matlab toolbox (circ_stats) that allows me to plot circular phase data, do tests on phase distributions, and to compare two distributions, but I would like to use Fieldtrip to extract the instantaneous
phase angles (radians or degrees) from the single trials for a given point in time using multitapers (which I believe is the preferred method for this, right?).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Browsing through the Fieldtrip discussion archive, I haven’t been able to find a dedicated Fieldtrip function for that, but I am sure that functions such as ft_mtmconvol do compute absolute phase at some point…<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Can anyone give me advise on how to achieve my goal?<o:p></o:p></span></p>
