Currently, we can write the observation markers to a file or to an array, but we can only read the markers from a file. Of course, one can always write an array to a file and proceed from there, but it'd be easier if we had a --from-array option. Allin, is there a reason for the lack of this option? ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
