<div dir="ltr">Dear Nithin,<div><br><div> Cluster statistic works both for MEG and EEG data since the machinery is the same . You can organize the Non-FT in the Fieldtrip style. Please not that FT have a data structure (channel*frequency*time ), so you need to transpose your data matrix first. Besides , you also need to define the layout of your channels , then you know the neighbors of channels (see <span style="background-color:rgb(247,249,250);color:rgb(0,0,0);font-family:Consolas,'Andale Mono',Menlo,Monaco,monospace;font-size:12px;text-align:justify;white-space:pre-wrap">ft_prepare_neighbours</span>) because clusters are formed on the basis of temporal, spatial and spectral adjacency. For more information, please have a look at the tutorial again <a href="http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_freq">http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_freq</a>.</div>

Subject: [FieldTrip] Question on Cluster-based permutation tests on<br>
time-frequency data<br>
Message-ID: <<a href="mailto:20140402T102301Z_155300170001@mprc.umaryland.edu" target="_blank">20140402T102301Z_155300170001@mprc.umaryland.edu</a>><br>

Dear All,<br>
I read the tutorial section on Cluster-based permutation tests on time-frequency data as well as the Maris and Oostenveld, Journal of Neuroscience Methods, 2007 report. I am interested in setting up a ERP experiment on EEG data in this regard I like the procedure and processing section of the tutorial, however I would like to know if there is any section for EEG, I understand that megplanar is specific for MEG.<br>
Also is it possible to use 3D matrix (TFR) (time, Freq channels ) non feild trip output to run the cluster based permutation tests.<br>
Looking forward<br>
Nithin<br>
