to remove the artifact as follows:</div>
<div class="">cfg = [];<br class="">
cfg.continuous = 'yes'; <br class="">
cfg.blocksize = 60; <br class="">
cfg.plotevents = 'no';<br class="">
cfg.preproc.demean = 'yes';<br class="">
cfg.layout = 'CTF151.lay';<br class="">
cfg = ft_databrowser(cfg, data);<br class="">
</div>
<div class="">cfg_artfctdef = cfg.artfctdef;<br class="">
</div>
<div class=""><br class="">
</div>
<div class="">cfg = [];<br class="">
cfg.artifactdef = cfg_artfctdef;<br class="">
cfg.artfctdef.reject = 'nan';<br class="">
data_clean = ft_rejectartifact(cfg, data);<br class="">
</div>
<div class=""><br class="">
</div>
<div class="">For two reasons, the specified regions of the artifact are not replaced by the null value:</div>
<div class="">1) The output printed in the command window is:</div>
<div class="">rejected 0 trials completely<br class="">
rejected 0 trials partially<br class="">
filled parts of 0 trials with NaNs<br class="">
filled parts of 0 trials with the specified value<br class="">
resulting 1 trials<br class="">
the call to "ft_rejectartifact" took 1 seconds<br class="">
</div>
<div class="">2) When I use the ft_databrowser function again for data_clean, basically the areas replaced with the null value should be invisible, which is not the case.</div>
<div class="">Can anyone explain to me what's the problem?</div>
<div class="">Thank you,</div>
