when using it with cfg.trl, and specifying a range that is not inside the data (as specified in data.sampleinfo), ft_refefinetrial returns nans. If the first trial in the data starts at sample 1, and if you specify a negative sample in trl, ft_redefinetrial returns a segment that is padded with nans at the end, rather than the beginning. Furthermore, it would be nice if ft_redefinetrial would give a warning about the nans, now it happens silently

I suspect this error to be in ft_fetch_data
