<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear list,
<div><br>
</div>
<div>I am having problems applying filterpadding when using ft_artifact_zvalue. </div>
<div><br>
</div>
<div>Could someone please explain what exactly the effect of filterpadding is, and in which cases I can apply it and in which not?</div>
<div><br>
</div>
<div>I intended to use it to avoid edge effects in the artifact detection. However, I get the following warning (only when applying fltpadding, my data does not actually contain NaNs):</div>
<div><br>
</div>
<div>
<div>Warning: data contains NaNs, no filtering or preprocessing applied </div>
<div>> In ft_warning (line 181)</div>
<div> In preproc (line 282)</div>
<div> In ft_artifact_zvalue (line 292)</div>
</div>
<div><br>
</div>
<div>These are my settings:</div>
<div>
<div>
<div>cfg = [];</div>
<div>cfg.trl = temptrl; % all trials</div>
</div>
<div><br>
</div>
<div>cfg.artfctdef.zvalue.channel = channel{ch}; % single channel</div>
<div>cfg.artfctdef.zvalue.cutoff = 3;</div>
<div>cfg.artfctdef.zvalue.fltpadding = 0.1;</div>
<div> </div>
<div>cfg.artfctdef.zvalue.bpfilter = 'yes';</div>
<div>cfg.artfctdef.zvalue.bpfilttype = 'but';</div>
<div>cfg.artfctdef.zvalue.bpfreq = [1 3];</div>
<div>cfg.artfctdef.zvalue.bpfiltord = 2;</div>
<div>cfg.artfctdef.zvalue.hilbert = 'yes';</div>
</div>
<div><br>
</div>
<div>Thanks!</div>

<div>Best,</div>
