[Andreas Widmann]

Dear all,

not directly related to your question and SIFT, but eegfilt is deprecated and I would recommend not using it any longer.

Best,
Andreas

I know that filtering is very bad for later VAR modeling, especially notch and high pass. Low pass is better (usually I use multi taper filtering to remove the noise lines and a low pass causal filter with cut off filtering of 100 Hz).
