At the risk of asking the obvious: have you 'selected and marked as artifact segments of data’ while interacting with the figure that pops up when you call ft_databrowser?

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