Epochs dict features don't work with save to fiff about mne-python HOT 8 CLOSED

... mhm, that's true. i did it so that the events get converted to keys. so restoring the names shouldn't be that difficult for the user. but to improve this, is there some field / corner in a fiff we could abuse for saving the mappings?

The dict features introduced in #229 are not compatible with saving to fiff in the sense that if you have an Epochs object with named events, save it, and load it again, the event names will be lost.

you can use a comment field as for Evoked. And serialize the dict in a string eg.

"visual:3;auditory:1"

wdyt?

not in comment but event_id tag or something...

@agramfort ... I don't find such a tag... and FIFF.FIFF_COMMENT is already used, as you implied. What about FIFF_DESCRIPTION?

from mne-python.

I would try writing a FIFF_DESCRIPTION tag in the FIFFB_MNE_EVENTS block.

that's what i already prepared, let's see what it does ;-)

I issued WIP #243 to fully support saving and reading the event_id. Closing this.
