Good afternoon!
I am new to EEG, a neurologist colleague asked me to automate some of her work and I am trying to understand the system.
Here’s the situation:
Neurologist selects alpha rhythm segments (3 pieces), then gives me raw materials and data on these segments (in .ann format).
Is it possible to sample these epochs (correct name?) in the MNE tool? For further fast Fourier transform
can you say something about what format the data and annotations are in (I’m not familiar with “.ann” files), and what program the neurologist used to create the annotations?
Generally speaking, in MNE-Python you would
- import the Raw data
- import the annotations
- get start and stop times from the annotations
- use start and stop times to extract chunks from the Raw data
- compute FFT
Probably extracting Epochs won’t work because Epochs must be exactly equal duration — if the neurologist is manually annotating the signal then the annotations are probably of varying durations.
