Hi Rachel,

What is the error you're receiving, and how are you calling ft_preprocessing? 

If the data is in raw format (incl a trial, time and label field), it should theoretically be possible to use ft_preprocessing on it, eg;
cfg = []
cfg ..
data = ft_preprocessing(cfg, raw)

where raw is your data as described above.
