pushd(as you prefer) into it. (If you are reading the electronic document and opened the window by pushing the button on the previous page, you will find yourself in the directory where the data is. We still recommend that you make a private directory for test purposes.)
You need some data in this directory to experiment on. To get some, do:
(If the files were not there, tell the person who installed SEPlib on your computer that they need to customize this document for your particular site by modifying the list of site-dependent paths kept in the file ``sitepaths.tex''.)
You should now be the proud owner of six files:
the actual data files, and
the so-called ``history'' files.
History files contain all the information about the data that is needed
by SEPlib programs, such as the path to the corresponding data file.
This way you can keep large data files in
places where they are more welcome.
We will introduce history files in detail in the next section.
Plot one of the data files by doing
Wiggle < Txx.H | TubeWhen you run the command above
Wigglecreates a plot which
Tubethen tries to display on your screen. Did it work? Hopefully your screen will look something like the one in Figure . (If when you try it ``
Tube'' does the plot using
Xtpen, like in the figure, exit the program by clicking on the
QUITbutton at the top of the window. If you are using some other sort of graphics device you may have to hit return or space to exit, or the program may simply exit when the plot is done without any prompting from you.) Try plotting
Wiggle < Txx.H | Tube
