Starting CASA¶
Once you have launched a Desktop session, it is straightforward to run CASA in a terminal.
To start a CASA-enabled terminal, first click on the Applications
menu at the top left corner of your screen
Click through the AstroSoftware and main CASA version to select the
specific version that you want to use. Every version of CASA back to
CASA 3.4.0 is available (this is the version of CASA which is tied to
the scripts distributed with ALMA Cycle 0 data on the archive; see link
here)
Clicking on your prefered version of CASA will open a terminal in which
you can run CASA in the standard manner (typing either casa or
casa --pipeline depending on the mode you wish to use). (NB: there
are two dashes before pipeline in the previous command)
You can open a regular (non-CASA) terminal by double-clicking the
terminal icon at the lower left side of the screen. Note that each
terminal has a label on top which denotes what type of terminal it is
(i.e., a plain terminal or the CASA version that is enabled). Only basic
linux commands are recognized in the CASA terminals, so it is preferable
to use a non-CASA terminal for all regular linux uses.
