Merge streams #79

Open niteshbhatia008 opened 2 years ago

niteshbhatia008 commented 2 years ago

I am looking for a way to merge multiple streams (like EEG, ECG, events) into a single stream or a dataframe in python. Any suggestions? Thank you.

Do you want to synchronize the streams in a way that they all have the sampling rate and samples are at the same time? There is a pull request on this topic: https://github.com/xdf-modules/pyxdf/pull/1 / https://github.com/sccn/xdf/pull/28

Does this describe your requirements or do you have something else in mind?

Do you really have these signals as separate streams? Usually, EEG, ECG, EOG, ... are associated with only one stream. Merging marker streams is already implemented in mnelab.io.xdf.read_raw_xdf (https://github.com/cbrnr/mnelab).
