<p>Hi All,</p>
<p>I am asking this question again since I tried on our <b>HPC server</b>, and still I need more memory for computation.</p>
<p>Do you have any idea how can I plot my signal in time-frequency?</p>
<p>I wrote down the detail in my following post.</p>
<p><br>
</p>
<p>Thanks!</p>
<p>Bahar</p>

<p>Hello All,</p>
<p>I am trying to apply wavelet on my signal to see HFOs in time-frequency plot.</p>
