Combining simultaneous data recording with different amplifiers

Hi list,

I have simultaneous MEG & EEG data where the EEG data were recorded on a
separate amplifier at a slightly different sampling frequency (2034.510
vs 2035.0 Hz).

Also, the samples are not necessarily aligned, but a common trigger is
present in both datasets.

Is there a standard way to combine these into a single Raw dataset? I
expect to low pass & interpolate on a common trigger-based time but
would like to anticipate possible artifacts.

Thanks for any comments or suggestions,
marmaduke

Marmaduk hi,

take a look at mne.epochs.add_channels_epochs to combine your data at the
epochs stage.
