ECG artifacts in MEG

[Stancak, Andrej]

Dear colleagues,

  I would like to clean MEG data from ECG artifacts. There is a routine
artefact_ECG.m enabling to detect the QRS complex in an ECG trace. The question
is whether there is (in FieldTrip or SPM8b) a method similar to the one
implemented in BESA which takes the template (basically an averaged QRS plus
interval encompassing the P and the T wave) and subtract it from each MEG (or
EEG) trace. Compared to ICA, this method works much faster although it
definitely may alter certain topographical features of MEG. 

 Best regards
 Andrej
