Questions about artifacts

• Do I need to resample my data, and if so, how is this to be done?
• How can I consistently represent artifacts in my data?
• How can I interpret the different types of padding in FieldTrip?
• How does the filter padding in preprocessing work?
• I used ICA on my MEG data from before 2012 and now FieldTrip crashes, why is that?
• Should I rereference prior to or after ICA for artifact removal?
• What kind of filters can I apply to my data?
• Why does my ICA eyeblink component look strange?
• Why does my ICA output contain complex numbers?
• Why is there a residual 50Hz line-noise component after applying a DFT filter?
