<p class="MsoNormal"><span lang="EN-US"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> I have a problem using the cfg.inputfile option with the ft_freqgrandaverage function.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> When I declare an cfg.inputfile and call the ft_freqgrandaverage(cfg) with only the cfg structure as an argument<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I get an error: ' cfg.inputfile should not be used in conjunction with giving input data to this function'
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> as if I would call the function with an inputfile AND a data structure (what is in fact not the case)<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US"> here a short example:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I calculated the time-frequency-spectra for all my subjects (like that: TFR1 = ft_freqanalysis(cfg, data))<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Now I wanne use the ft_freqgrandaverage function to average time-frequency-spectra over subjects.
