[Mne_analysis] MPRAGE vs multi-echo FLASH

[Mikołaj Magnuski]

        External Email - Use Caution        

Thanks Alex,

I am also looking for some references or opinions with respect to the gain
in source localization accuracy/correctness when adding FLASH to normal T1
MPRAGE. Especially if one has only EEG with a modest number of channels
(64). I am wondering if adding FLASH, which is much longer than MPRAGE,
does make a noticeable difference in such a scenario.
Any suggestions and opinions would be greatly welcome.
