<div dir="ltr">Dear Natan,<div><br></div><div>If you go down to 1 Hz with 3 cycles, then your window length will be longer than 3 second. It'll make huge difference in the output. You should see much narrower time window when you use 1-50 Hz condition, which should explain at least one of the reasons why you received a very different impression. If you find a difference other than this (oh, it'll change the cycles too; you should have 3 times (?) more cycles around 50 Hz and the plot should look horizontally stretched...) and you need an explanation let me know.</div>

Hi!<br>
<br>
Recently I was using 'newtimef' function to compute significant
differences between two groups. I set frequency to 5-45 Hz, and got
fine results. <br>
But after that I changed limits (nothing more) to 1-50 Hz all
results were all different! Could someone give a hint why is that? I
understand the option 'freqs' does something more than 'ylimit', but
what?<br>
<br>
Thank you for help!<br>
<br>
Best regards!<br>
Nathan<br>

<br>
P.S.<br>
This is the function I use:<br>
<br>
[ersp, it, powbase, times, freqs, erspboot,itcboot] = newtimef(
(EEG_group1.data(channel,:), EEG_group2.data(channel,:) ), ...<br>
EEG_group1.pnts, [EEG_group1.xmin, EEG_group1.xmax]*1000,
EEG.group1.srate, ...<br>
'cycles', [3, 0.5], 'plotitc','off', 'plotersp', 'on', <b>'freqs',
[5 45],</b> 'scale', 'log', 'alpha', 0.05);<br>
<br>
<br>
