[Mne_analysis] EEG Data Conversion

[Denis A. Engemann]

Hi Isaiah,

yes this is correct.
Take look at the documentation string to get an idea how to use it,
basically you pass the data matrix, the sampling rate, a list of channel types, like ['eeg'] * 128 for 128 EEG channels and that's it for constructing a Raw object whose .save method you can then use to create a fiff file.

Please let me know how it goes.

HTH,
Denis

Also, we know the sampling rate information. So can we use some tools (e.g. mne.io.RawArray, mne.EpochsArray and mne) to convert into fiff format?

If you cannot find a converter for whatever file types these are, but you are able to read the files with some toolbox: you could read in those data files and replace all of the fields in the raw sample data set with your data. This is something I only recommend for advanced users as there are a lot of details you need to keep track of.
