[Mne_analysis] [concatenation of annotated epochs]

[Virginie van Wassenhove]

        External Email - Use Caution        

Hi folks,

I am getting the error pasted below when trying to concatenate epochs that
have been baselined and then cropped. Richard which included the
annotation "(baseline period was cropped after baseline correction)" when
doing so:

[<EpochsFIF |  45 events (all good), 0 - 1 sec, baseline -0.2 – 0 sec
(baseline period was cropped after baseline correction), ~42.5 MB, data
loaded, with metadata,
  '11': 45>,

The limitation appears known in the error so my question is this an easy
fix or should I find a work around?

Many thanks,
Virginie
