Tomographic file has header? (y,n(dflt)): n

    Files assumed to be labelled  basename.ext,
    basename  is limited to 255 characters maximum,
    ext       is a numerical designator lying between 000 and 999
    It is assumed that the files have consecutively numbered extensions
        ie.  000 -> 056,  or   021 -> 049
