<div dir="ltr">Dear Tyler,<div><br></div><div>It uses PCA for decomposition, and eye blinks tend to have high and often the highest amplitude among other sources, that is why... actually I wish it does not remove eye blinks because I want to let ICA take care of it. Anyways I'm happy that you like it. I've also heard other users really like it too. When I heard the idea of this approach from Christian I was deeply impressed and thought that this is going to be the champion method.</div><div><br></div><div>By the way I've heard the report that pop_rejcont() has a problem and when it causes errors clean_rawdata() falls back to its own function and reject data and delete event info. Ramon fixed it today and updated EEGLAB, so I strongly recommend you update EEGLAB. When you need to use the older version of EEGLAB, carefully watch the log. The pop_rejcont() error occurs only when the last datapoint is selected for rejection (or something similar). Again, now it is fixed though.</div><div><br></div><div>Makoto</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Oct 1, 2014 at 4:49 PM, Tyler Grummett <span dir="ltr"><<a href="mailto:tyler.grummett@flinders.edu.au" target="_blank">tyler.grummett@flinders.edu.au</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>Thank you to both of you.</div>

<div>The function is awesome, it's really good at getting rid of eye blinks. Is that by design? Or a very convenient coincidence? Haha</div>

<div dir="ltr">Hi Tyler and Makoto,
<div><br>
</div>
<div>yes this is a zero-phase and non-causal FIR filter. Note that you can disable it and perform your own drift correction if you are concerned about any issues with information flow analysis.</div>

<div dir="ltr">Dear Tyler and Christian,

</div>
<div>Theoretically yes, as it most likely uses zero-phase non-causal filter i.e. a spike like a needle will be decomposed into a triangle, the left half of which is 'information from the future'. Tim recommends slope fit and subtract solution he supports in
SIFT (that's for high-pass; for low-pass, use cleanline).</div>
<div><br>
</div>
<div>Christian, is clean_rawdata high-pass filter zero-phase and non-causal? Or was it zero-phase and causal?</div>

Hello eeglabers, specifically makoto,<br>
<br>
I was just wondering if you used the 'initial high pass filter' in the function clean_rawdata, would it interupt connectivity analyses?<br>
