Hi Mona,
<div class=""><br class="">
</div>
<div class="">I think that you first need to look into what you actually want to achieve. From the context of this thread it seems that you want to visualise data that has been collected with a ‘neuromag306’ MEG device, which is further supported by the fact
that you mentioned having an ‘.fif’ file. However, you don’t mention whether you have read in actual data to-be-plotted. You only mention that you have read in the header information (as per ft_read_header). Using ft_read_data is not going to do the trick.
In order to use the higher level plotting functions, you need to create a data object as per ft_preprocessing. Please refer to the tutorial documentation on <a href="http://www.fieldtriptoolbox.org/tutorial/natmeg/preprocessing/" class="">http://www.fieldtriptoolbox.org/tutorial/natmeg/preprocessing/</a>,
for instance.</div>

Yes, I have tried the neuromag306all.lay and neuromag306cmb.lay. My issue is I don’t know what format/data structure my data needs to be in order to use these layouts since the example neuromag306.mat was empty so didn’t work with the neuromag layouts. I
did read in my neuromag data using the ft_read_header() and ft_read_data() but not sure how to use it with the plotting function ft_multiplotER(), ft_topoplotER() and/or ft_topoplotTFR().

Hi Mona,
<div class=""><br class="">
</div>
<div class="">Have you tried the layout files that are contained in fieldtrip/template/layout.</div>
<div class="">I think that there should be a few that would suit your needs.</div>

Hi:<br class="">
<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span>I’m working my way through the plotting tutorial at
<a href="http://www.fieldtriptoolbox.org/tutorial/plotting/" class="">http://www.fieldtriptoolbox.org/tutorial/plotting/</a>. I would like to use the neuromag306all.lay layout to plot the data. I tried the neuromag306.mat from ftp but that didn’t work; it
seems the data read in from neuromag306.mat doesn’t actually contain any data:<br class="">
