[Eeglablist] Running the ADJUST Algorithm When We Have Partial Coverage of the Brain

[Marco Buiatti]

Dear eeg researcher,

As ADJUST is based on spatial (and temporal) features, it does not work if
your spatial coverage does not include at least one channel in the scalp
areas predetermined in the algorithm.

You might try to disable some of the spatial features by reprogramming
ADJUST's scripts, but in that case please double-check the results!

Best,

Marco Buiatti (ADJUST main developer)
