Resampling a Non-Uniform Signal

Support & Discussions

Hi,

I have a signal that is non-uniformly sampled. It is mostly sampled at 300Hz but the interval between samples can be irregular hence are not always 1/300.

Can MNE resample a non-uniform signal to be uniform?
Does mne.filter.resample have a parameter that takes this into account?

Thanks,

Josh

MNE is not designed to work with non-uniformly sample signals, so no I don’t think you’ll find a tool to do that here.
However, you can first resample your signal uniformly with a different tool (I would be surprised if scipy does not have some function to do that) and then import your signal in MNE using e.g. RawArray.
