The best way to use XPP is from the command line as this gives you many more options and much more flexibility. Then click on the Applications Terminal menu item on the menus. This will bring up a new terminal window. The default for the XTerm is to be in your Home directory.For me, the default font is way way too small, so with your mouse in the window, press the control key and put two fingers on the mouse pad to bring up a little menu to get a bigger font. If you did what I said earlier, then you should have the xppmac folder on your Desktop. The second command just lists all the ODE files. If you are going to use XPP a lot, it is good to maintain different folders with the ODEs and other files like table files and set files all together. To fire up the old lecar.ode model in XPP This way you can always navigate to them and run XPP from the command line. You may want to customize your defaults so that XPP looks the way you want it to when you run it.
I generally get rid of some defaults (such as the Bell) and make the fonts bigger so I can see them. This is done by creating a plain text file in your HOME directory called. I provide the following example ( example.xpprc tutorial=0 You can use textedit to create the file (or your favorite editor) but make sure it is plain text and make sure that the. This automatically turns the bell off, the fancy menus (grads) off, and the tutorial off. I also change the drawing window color from white to a kind of ivory and the drawing foreground color to a brown. I also use much bigger fonts and change some of the AUTO defaults. Finally I change some of the postscript defaults. You can find out more about these options in the xpp_sum.pdf document. The only way to change the fonts and the colors of XPP is via the. xpprc file or through the command line since these are processed before the X11 server starts. ODE files are just descriptions of what you want to solve. They are plain text files that have the extension. Expressions like special name=expression like convolutions etc.Expressions of the form name=expression are evaluated first and in the order they are written, so if one expression makes a reference to another, then make sure they are ordered appropriately.There is a specific order to the way things are evaluated in ODEs.Always end your ODE file with done If you do you can write lots of instructions after this that will be ignored by the program but may be useful for the user who reads the ODE file.It is generally bad to put spaces between parameter/initial conditions and their values (although this is now OK), so write iapp=0.1 instead of iapp = 0.1.There should be a space after the symbol in all options statements.XPP is case-insensitive so that aBc and ABC are the same to XPP.There are a few rules that are really important to understand: ode but can have any extension yiu want as XPP ignores it.
#MAC UPDATE XQUARTZ HOW TO#
Look at the many examples to see how to construct your own ODE files.
#MAC UPDATE XQUARTZ MAC#
You see something like "Illegal Instruction".There are many XPP tutorials out there to help you get started Problems #Install xquartz on mac how to# In this case, you are probably using a version of the OS that is older than 10.7.5.
#MAC UPDATE XQUARTZ UPGRADE#
You probably should upgrade to the most recent OS.
It is possible for me to make a binary for some older machines, so in this case contact me.
