<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt;mso-fareast-language:EN-US">Depending on what level you have your t-maps (sensor level, source level, or something else), you can manually create the FieldTrip data structure. All you need is to
arrange your t-map as NxM matrix, a vector with the N channel names, and a vector with the M dimension, usually time or frequency. Finally, you specify the “dimord” according to one of the datatypes, e.g., “chan_time” if the data is channelled by time points.
The details on what you need and what the data fields should be named are explained here:

<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt;mso-fareast-language:EN-US">For example, if you have a single t-value per channel location in a standard EEG cap, you would export the N channels x 1 “t-map” and the channel names. Once you have
arranged it according to the FieldTrip naming conventions, you can use ft_checkdata to see if the structure is “valid” in FieldTrips view or if something is still missing.<o:p></o:p></span></p>

</span><span style="font-family:"Apple Color Emoji";color:black">🙂</span><o:p></o:p></p>
<p class="elementtoproof"><o:p> </o:p></p>
<p class="elementtoproof"><span style="font-family:"Lucida Sans Unicode",sans-serif;color:black">I have contrast and t-maps generated in SPM-EEG, and I've been finding it challenging to plot these in SPM while allowing for some customization (even basic ones
like adjusting the scale or plotting multiple time points).</span><o:p></o:p></p>
<p class="elementtoproof"><o:p> </o:p></p>
<p class="elementtoproof"><span style="font-family:"Lucida Sans Unicode",sans-serif;color:black">Since there does not seem to be a simple solution to achieve this, I was considering using FieldTrip for plotting these statistical maps. I found the function spm2fieldtrip,
but it only seems to handle the conversion of raw data. I was wondering if any of you have experience or insights on using FieldTrip for plotting SPM statistical maps directly, without the need to redo the entire analysis on FieldTrip. </span><o:p></o:p></p>
<p class="elementtoproof"><o:p> </o:p></p>
<p class="elementtoproof"><span style="font-family:"Lucida Sans Unicode",sans-serif;color:black">Any tips or guidance would be greatly appreciated..</span><o:p></o:p></p>
