The way to specify a duration would be to use a 2nd <port> element that sets all bits to low again at the desired point in time. E.g. / stimulustimes = [...; 500=mysignal; 600=allbitstolow; ...] with <port mysignal> / items = ("00000001") ... </port> <port allbitstolow> / items = ("00000000") ... </port> would result in a signal duration of 100 ms.
