Hi Christine,
<div class=""><br class="">
</div>
<div class="">Are you sure that the tmpdata_small and data_segm_offsetcorr are consistent with respect to each other? As long as this is not the case, I am not surprised that fieldtrip ‘misbehaves’.</div>
<div class=""><br class="">
</div>
<div class="">Best,</div>

<font size="2" class="">Good morning,<br class="">
<br class="">
I discovered that using ft_databrowser & ft_rejectartifact to preprocess my EEG data, often the wrong number of trials is rejected. This is the code I am using and it inherits data resulting from ft_redefinetrial.<br class="">
<br class="">
<font face="Courier New" class=""> cfg = [];<br class="">
cfg.latency = [-2 2];<span class="Apple-converted-space"> </span><font color="808000" class="">% period of interest</font><br class="">
tmpdata_small = ft_selectdata(cfg,data_segm_offsetcorr);<br class="">
<br class="">
cfg = [];<br class="">
cfg.layout = layout2;<br class="">
cfg.showlabel = 'yes';<br class="">
cfg.channel = 'EEG';<br class="">
cfg.gradscale = 0.04;<br class="">
cfg.continuous = 'no';<br class="">
<font color="808000" class=""> % filtering only for artifact rejection</font><br class="">
cfg.preproc.lpfilter = 'yes';<br class="">
cfg.preproc.lpfreq = 40;<br class="">
<br class="">
cfg_databrowser = ft_databrowser(cfg, tmpdata_small);<br class="">
data_segm_offsetcorr = ft_rejectartifact(cfg_databrowser, data_segm_offsetcorr);<br class="">
<br class="">
<font face="Calibri" size="3" class="">If I now, for example mark 10 trials in the databrowser and then run ft_rejectartifact, it tells me:<span class="Apple-converted-space"> </span><br class="">
<br class="">
<font face="Courier New" size="2" class="">detected 10 visual artifacts<br class="">
rejected 8 artifacts completely<br class="">
<br class="">
<font size="3" class=""><font face="Calibri" class="">Something seems to be wrong here as I clearly marked 10 artifacts (don't really care whether they are visual or not), but only 8 are removed. The problem gets worse when I call the function a second time,
which is when usually none of the marked artefacts are rejected at all.<br class="">
<br class="">
Any idea where the problem could be?<br class="">
<br class="">
Many thanks!<br class="">
Best,<br class="">
