Turns out I didn't set `baseline=None`,  indeed I don't want it to be baseline corrected, this solved the problem, thanks a lot !

Strangely once I epoch the envelope with mne.epoch() using some equally spaced stimulus releated events, the resulting epochs contain some negative value in their entries. But is does not seems that epoching shift the origin x axis or does it?

Did you set `baseline=None`? The default<https://mne.tools/dev/generated/mne.Epochs.html#mne.Epochs> is `baseline=(None, 0.)` which would mean that your data are being baseline corrected (which you probably don't want).
