Time Frequency analysis for Raw

💬 Support & Discussions

Hey Everyone,

I was wondering why time frequency analysis was not implemented for raw objects. Is it because there is some methodological issue behind this, or simply because few people have the use for it?

Thanks for you help,
Best,

it is on our roadmap. Mainly it has not yet been implemented yet because demand is low and computational cost can be very high (depending on length of Raw object). There are functions for time-frequency analysis of NumPy arrays, and you could in theory convert a Raw to a single (possibly very long) epoch, so it is technically possible to do it with a bit of data munging and enough memory/computation time:
