data = [] data.label = {'a'} data.time = {1:1000}; data.trial = {zeros(1,1000)}; cfg = []; ft_rejectvisual(cfg, data) gives an error (as reported On 22 Jan 2014 by Ozan Ça?layan).

The reported error is probably due to the fact that there is just 1 trial, not because it contains all zeros. The all zero probably fails due to the variance being nan, the 1 trial fails because there's just one trial. A single trial of all zeros therefore probably fails for two reasons. ;-)

I think that in principle the function should work on the 1 channel / 1 trial case (even if the numeric data are non-zero).
