Post-Installation Setup for CASA Macintosh Intel

Your Shell Environment

CASA uses an enhanced Python environment (an open-source shell called iPython) for its primary user interface. You use this iPython shell from a Terminal or X11 window to set up data-processing tasks.

Anyway, you need to let your shell environment know about the CASA setup. The easiest way to do this is to add a line to your shell initialization script:

source /opt/casa/

(or source /opt/casa/casainit.csh if you use tcsh)

I added this line to my $HOME/.profile script, so that every Terminal window that I open calls this initialization script.

Running CASA for the First Time

To start CASA, first source the /opt/casa/ script as described above, then issue the casapy command in a Terminal window.

The first time you run casapy, it will configure the iPython environment. You may see warning messages about fonts. I think these are generally safe to ignore. Once that is done, you should see something like

Welcome to IPython. I will try to create a personal configuration directory
where you can customize many aspects of IPython's functionality in:


Successful installation!
Please press <RETURN> to start IPython.

And you can press the return key to get into the casapy shell.

Release Notes

ASAP has been incorporated into CASA for this release.
