GFP equation

10

Looking quickly through GFP stuff, this is the equation I find in MNE: ``` np.sqrt((data**2).mean(axis=1)) ``` And this is in pycrostates: https://github.com/vferat/pycrostates/blob/ff3da2b02024d5a54d09878d87d14834859d38dd/pycrostates/preprocessing/extract_gfp_peaks.py#L160 @vferat Any opinion here?

Similar to an epoch object where you can do `epochs["my condition"]`, an `EpochsSegmentation` should be indexable. Suggested by Vincent today ;) c.f. https://github.com/mne-tools/mne-python/blob/6733cae2a0765da9ec1b67a98937839d4cd9aadf/mne/utils/mixin.py#L78-L144
