Description
Ideas from previous discussions:
- Unify handling of
rank
betweenmne/cov.py
andmne/viz/evoked.py:plot_evoked_white
(esp.mag
/grad
parameters) (MRG: Add whitening to plots #4799) - Low rank computation to speed up fitting (esp. for SSS data), adapt from unused bits of [MRG] FIX/MAINT/ENH Covlove clip rank #4637 (MRG: Do regularization in PCA space #5481)
- Have
maxwell_filter
with movecomp set then_components
insss_info
to the proportion of time a given MPM was used. (Currently it's binary, and it only uses the destination position.) - Have
maxwell_filter
setnfree
based on the effective/estimated rank of the raw data, or from thresholding the floatn_components
? - Improve rank estimation code to deal with movement compensated data (which has time-varying rank) and also ICA (which can reduce rank but isn't stored in
info
)
