[FieldTrip] unit ft_freqanalysis

[Arjen Stolk]

Hi Giulia,

Baseline correction method 'relchange' computes the relative change
according [ (task-baseline)/baseline ], i.e. a ratio centered around zero.
If you multiply with 100, you get the relative change (from baseline)
expressed in percentages.

best regards,
Arjen
