<p class="MsoNormal">Dear Fieldtrippers,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m currently working on an MEG dataset and have so far done automatic rejection of bad channels using Maxfilter and then done ICA-based artefact reduction (eyeblinks and heartbeat) in MNE Python. I now have my data in Fieldtrip trial structures.
 What is left is to remove trials that are outliers/noisy because the subject moved/coughed/etc. I have tried to use ft_visinspect with variance as metric, but the issue I have is that the variance is displayed in actual units (e.g. 1e10^23) rather than in
 terms of standard deviations. This is problematic, as my trial rejection will be based on my subjective decisions that some trials look like outliers and not others. What I would like instead is to just do something like “discard trials where the amplitude
 is more than X standard deviations above or below the mean”, which is reproducible. Is this way of rejecting trials implemented in FT? I have seen the tutorial on automatic artefact rejection, but it looks more like something that would be useful for removing
 e.g. eyeblinks.<o:p></o:p></p>
