[FieldTrip] more on artfifact rejection

[Robert Oostenveld]

Dear Kambiz

Although other people's preferences might differ, I would suggest that you use visual inspection to detect your artifacts. For trial-based data you cannot apply filter padding. The consequence is that the automatic artifact detection routine implemented in fieldtrip is likely to suffer from false alarms at the edges of your trials, and reduced sensitivity away from the edges. 

Visual detection of artifacts can be done using ft_rejectvisual (check out the three options it has), and using ft_databrowser.

best regards,
Robert

> Greetings - this has been an informative discussion. My question remains is , what is the consensus on an approach for automatic artifact rejection with trial (CTF) data? E.g., could one use the artifact rejection section of Michael's code without any padding? I have not found any tutorials or suggestions on how to use the artifact rejection tools on trial data...have I missed something.
