Dear Fieldtrip members,
<div><br>
</div>
<div>I would like to apply to my data a bandpass filter from 0.016 (or at least 0.1) to 30 Hz </div>
<div><span style="font-family: Courier; font-size: 10px; "><br>
</span></div>
<div><span style="font-family: Courier; font-size: 10px; ">bpfilterRange = [.1 30];</span></div>
<div><br>
</div>
<div>However, it seems that Fieltrip doesn't accept small high-pass filter values. I have the following mistake : </div>
<div><br>
</div>
<div>
<div><br>
</div>
<div><font color="#b51a00">Error in preproc (line 299)</font></div>
<div><font color="#b51a00">if strcmp(cfg.bpfilter, 'yes'), dat = ft_preproc_bandpassfilter(dat, fsample, cfg.bpfreq, cfg.bpfiltord,</font></div>
<div><font color="#b51a00">cfg.bpfilttype, cfg.bpfiltdir, cfg.bpinstabilityfix); end</font></div>
<div><font color="#b51a00"><br>
</font></div>
<div><font color="#b51a00">Error in ft_preprocessing (line 559)</font></div>
<div><font color="#b51a00"> [cutdat{i}, label, time{i}, cfg] = preproc(dat, hdr.label(rawindx), tim, cfg, begpadding, endpadding);</font></div>
<div><font color="#b51a00"><br>
</font></div>
<div><font color="#b51a00">Error in preprocessing_Libet (line 70)</font></div>
<div><font color="#b51a00"> allData_prepross = ft_preprocessing(cfg);</font></div>
</div>
<div><br>
</div>
<div>I also tried with 0.2, 0.5, and the minimum acceptable I found was 0.9, which is quite high.</div>
<div><br>
</div>
<div>I wonder if the problem comes from my data (but I had no problems on others programs) or if there is a way to apply 0.1 high-pass filter on Fieldtrip?</div>
<div><br>
</div>
<div>Thank in advance, </div>
<div><br>
