<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Evryone,
<div>I was wondering why do i get this type of warnings when running ICA on my data.</div>
<div>this is the script I am using:</div>
<div><br>
</div>
<div><br>
</div>
<div>
<div><i>cfg.resamplefs = 300;</i></div>
<div><i> cfg.detrend = 'no';</i></div>
<div><i> datads = ft_resampledata(cfg, data_clean);</i></div>
<div><i><br>
</i></div>
<div><i> cfg=[];</i></div>
<div><i> cfg.bpfilter='yes'; % bandpass , use low freqs for alpha compponents </i></div>
<div><i> cfg.bpfreq = [0.5 30];</i></div>
<div><i> datatmp= ft_preprocessing(cfg, datads)</i></div>
<div><i><br>
</i></div>
<div><i><br>
</i></div>
<div><i> cfg.method = 'runica';</i></div>
<div><i> cfg.runica.maxsteps =30;</i></div>
<div><i> comp_filt = ft_componentanalysis(cfg, datatmp);</i></div>
<div><i> </i></div>
<div><i> clear datads</i></div>
<div><i> </i></div>
<div><i> </i></div>
<div><i> cfg = [];</i></div>
<div><i> cfg.unmixing = comp_filt.unmixing;</i></div>
<div><i> cfg.topolabel = comp_filt.topolabel;</i></div>
<div><i> comp_origin = ft_componentanalysis(cfg, data_clean);</i></div>
<div><i> </i></div>
<div><i> clear comp</i></div>
<div><i> </i></div>
<div><i> cfg = [];</i></div>
<div><i> <span style="font-size: 10pt;"> cfg.viewmode = 'component';</span></i></div>
<div><i> cfg.layout = 'CTF275.lay'; </i></div>
<div><i> ft_databrowser(cfg, comp_origin)</i></div>
<div><i><br>
</i></div>
<div><i> </i></div>
<div><i> <span style="font-size: 10pt;"> cfg = [];</span></i></div>
<div><i> cfg.component = input('bad comps = ');</i></div>
<div><i> meg_ica = ft_rejectcomponent(cfg, comp_origin,data_clean);</i></div>
</div>
<div><br>
</div>
<div><br>
<div>later on after having selected the bad components i get these messages :</div>
<div><br>
</div>
<div>Warning: unexpected channel unit "unknown" in channel 158 (i get this for all the channels but i copy-pasted just one of them for obv reasons)</div>
<div>
<div>Warning: copying input chantype to montage </div>
<div>Warning: copying input chanunit to montage </div>
