[Mne_analysis] DICS for each epoch in 0.16.1

[Marijn van Vliet]

Hi Jeff,

the old dics_epochs function uses the CSD to compute a spatial filter and then applies to filter to the epoched signal. We have chosen not to continue this functionality at this point, because the result is very confusing, i.e. the result is not the signal power at a given frequency over time. If that is your aim, I recommend computing the CSD on all epochs, feed that into make_dics to get the spatial filter, then compute CSDs for each individual epoch and obtain power estimates by calling apply_dics on them. If obtaining power estimates is not your aim and you know what you’re doing, feel free to keep using the dics_epochs function for the time being.

best,
Marijn.
