CIAO 4.8 Science Threads
The CIAO environment must be set up in each terminal window where you want to run the software. This thread shows how to create a startup alias, as well as how to handle the case where you have both CIAO 3.4 and CIAO 4.8 installed. We also discuss how to start FTOOLS and CIAO so that they can be used together in the same terminal.
Last Update: 9 Dec 2015 - Review for CIAO 4.8

To use the CIAO software, you must first run a setup script. There are a few things to note about setting up the alias:
These examples have CIAO installed in the directory /soft/ciao-4.8/. The location of the CIAO software on your system may be different.
If you have more than one version of CIAO installed, you may wish to version the alias to distinguish between them.
The alias syntax depends on the shell (tcsh, csh, bash); see this FAQ for help in determining which shell you are using.
csh/tcsh users should add the following
to their $HOME/.cshrc file.
alias ciao "source /soft/ciao-4.8/bin/ciao.csh"
bash users should add the following
to their $HOME/.bashrc file.
alias ciao="source /soft/ciao-4.8/bin/ciao.bash"
ksh users should add the following
to their $HOME/.login file.
alias ciao=". /soft/ciao-4.8/bin/ciao.ksh"
Users can create the file if one does not already exist. These are simply text files that can be edited with the users favorite text editor (emacs, vi, gedit, etc.).
Then you can just type "ciao" to start the software:
unix% ciao CIAO configuration is complete... CIAO 4.8 Thursday, December 3, 2015 bindir : /soft/ciao-4.8/bin CALDB : 4.7.0
It is only necessary to do this once per terminal/window.
The startup script will not allow you to restart CIAO in a session, instead reporting the following:
unix% ciao ERROR: The current environment is configured for: CIAO 4.7 Thursday, December 4, 2014 bindir : /soft/ciao-4.7/bin CALDB : 4.6.9 Please use the '-o' option to override the previous setup.
If you wish to restart CIAO, then you should either start CIAO in a different window or use the override option ("-o"):
unix% ciao -o CIAO configuration is complete... The CIAO setup for this window has changed from CIAO 4.7 Thursday, December 4, 2014 bindir : /soft/ciao-4.7/bin CALDB : 4.7.0 To: CIAO 4.8 Thursday, December 3, 2015 bindir : /soft/ciao-4.8/bin CALDB : 4.7.0
Users have to be careful about switching between different version of CIAO because of differences in parameter files. The default local parameter file directory name in CIAO-4 is different, which makes it easier to run both CIAO 3.4 and CIAO 4.8 in separate terminal windows on the same machine. For example, assuming CIAO 3.4 is installed in /soft/ciao3.4 and CIAO 4.8 in /soft/ciao:
unix% alias oldciao 'source /soft/ciao3.4/bin/ciao.csh' unix% oldciao CIAO configuration is complete... CIAO version : CIAO 3.4 Sunday, November 19, 2006 Proposal Toolkit version : Cycle 9 Sunday, November 19, 2006 bin dir : /soft/ciao3.4/bin unix% echo $PFILES /home/username/cxcds_param;/soft/ciao3.4/contrib/param:/soft/ciao3.4/param unix% paccess dmgti /home/username/cxcds_param/param/dmgti.par
and in a different window, using the suggested alias to start CIAO 4.8:
unix% ciao CIAO configuration is complete... CIAO 4.8 Thursday, December 3, 2015 bindir : /soft/ciao-4.8/bin CALDB : 4.7.0 unix% echo $PFILES /home/username/cxcds_param4;/soft/ciao-4.8/contrib/param:/soft/ciao-4.8/param unix% paccess dmgti /home/username/cxcds_param4/dmgti.par
You can see that the information is being read from two separate parameter file locations.
Both CIAO and FTOOLS use parameter files to store parameter values for tools, and provide tools for manipulating these files (e.g. plist, pset, punlearn; they have the same name in both systems). The location of the parameter files is taken from the $PFILES environment variables for CIAO and FTOOLS.
We recommend that you start FTOOLS before CIAO. Here is an example of starting version 6.x of FTOOLS and CIAO 4.8:
unix% setenv HEADAS /soft/lheasoft/headas/x86_64-pc-linux; \ source $HEADAS/headas-init.csh unix% ciao CIAO configuration is complete... CIAO 4.8 Thursday, December 3, 2015 bindir : /soft/ciao-4.8/bin CALDB : 4.7.0
Change the HEADAS path to match your local installation. Note this syntax applies only to C Shell variants (csh, tcsh); for further details on starting FTOOLS, including other shells, refer to the Installing HEAsoft instructions.
The $PFILES variable has been set up to use both the CIAO and FTOOLS directories:
unix% echo $PFILES /home/username/cxcds_param4:/home/username/pfiles;/soft/ciao-4.8/contrib/param: /soft/ciao-4.8/param:/soft/lheasoft/headas/x86_64-pc-linux/syspfiles
