<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have an MEG experiment in which I expect my stimulus to incite multiple reactions. I have run the experiment so that the stimulus is applied at two different intensities. I would like to use the lower intensity stimulus response as
a 'mask' for the higher intensity response.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I can calculate the power spectrum for both intensities and find the difference.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Although I can generate an ft_multiplot for each individual power spectrum, I cannot generate a ft_multiplotTFR of the difference between the two spectra.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I get the following error messages:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Error using ft_checkdata (line 366)<o:p></o:p></p>
<p class="MsoNormal">This function requires freq data as input.<o:p></o:p></p>

<p class="MsoNormal">Error in ft_multiplotTFR (line 135)<o:p></o:p></p>
<p class="MsoNormal">data = ft_checkdata(data, 'datatype', 'freq');<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
