cfg = [];

should do that for you. See also

Once the data is in memory (either segmented in many small pieces or one large piece), you can use ft_redefinetrial to change the segmentation (e.g. cut trials into shorter pieces or change from stimulus locked to response locked). In your case you can pass the trl to ft_redefinetrial.
