[Mne_analysis] MPRAGE vs multi-echo FLASH

Hi Mikołaj,

a proper T1 MPRAGE is mandatory to segment the cortex and to see over which
region in the brain you have activation.

the Flash images are a bonus if you want to have a fine segmentation
of the skull
surface for more accurate forward modeling.

My understanding is that both are useful for EEG source reconstruction because FLASH is better at reconstructing skull boundaries and MPRANGE is better at reconstructing the cortex, but I couldn't find any particular info on that, so please correct me if I'm wrong.
