For example, it's fine to use 'cycles', [3 0.85], 'freqs', [8 50] (this makes 1117ms window length) for MMN paradigm in which SOA is 500 ms.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Makoto</div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Oct 18, 2015 at 9:20 PM, Akshay Maggu <span dir="ltr"><<a href="mailto:akshaymaggu86@gmail.com" target="_blank">akshaymaggu86@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr">Hi all, <div><br></div><div>How valid or how accurate would a time-frequency decomposition be with epochs time range of -0.1 to 0.8 sec?
