CIAO is supported on a number of operating systems, which are listed on the Platform Support page. Certain system requirements are necessary to successfully install and run CIAO; review these system requirements before continuing with the installation.
Users should be aware of these installation items before installing CIAO 4.15.2. Additional problems which are seen less frequently are listed on the Installation & Smoke Tests bug page.
Remove old parameter files
With every new CIAO release, some parameter files have changed: new parameters may be added and occasionally old ones removed or renamed. Deleting or renaming the local parameter directory ensures that the correct parameter files will be accessed the first time a tool is run:
unix% rm ~/cxcds_param4/*
Downloading the Software
For a standard CIAO installation, you need the following packages:
Contains the CIAO tools, libraries, parameter files, and help files. Also contains the pre-compiled off-the-shelf (OTS) programs required to run CIAO.
The relationship between <OS> and the supported operating systems is given in the following table:
<OS> Operating system Linux all 64-bit Linux w/Python 3.9 macOS 64-bit macOS 10.15 (Catalina through Ventura) w/Python 3.932bit Linux and OSX 10.6.8-10.14: End of Life
CIAO is no longer available for 32bit Linux nor for OSX 10.14 (Mojave) and earlier. The platform support page describes the operating systems that can be used with CIAO.
Chandra Calibration Database (CALDB) v4.10.7
Some calibration products are packaged separately, due to the larger file size and specific analysis uses for them. Users may opt to include the ACIS background files and/or HRC background files when installing the CALDB. This thread includes only the ACIS background tarfile.
Scripts and Modules Package ciao-4.15-contrib-3.tar.gz
The files are retrieved with wget. In this example, the 64-bit Linux files (<OS>="Linux") are retrieved; change the <OS> value to match your operating system. Save the tarfiles to a location - /soft/download/ in this example - that is accessible from where you wish to install CIAO.
unix% mkdir /soft/download/ unix% cd /soft/download unix% wget https://cxc.cfa.harvard.edu/ciao-install/ciao-4.15/Linux/ciao-4.15-bin-core-Linux.tar.gz unix% wget https://cxc.cfa.harvard.edu/ciao-install/ciao-4.15/Linux/ciao-4.15-bin-obsvis-Linux.tar.gz unix% wget https://cxc.cfa.harvard.edu/ciao-install/ciao-4.15/Linux/ciao-4.15-bin-sherpa-Linux.tar.gz unix% wget https://cxc.cfa.harvard.edu/ciao-install/ciao-4.15/Linux/ciao-4.15-bin-tools-Linux.tar.gz unix% wget https://cxc.cfa.harvard.edu/ciao-install/ciao-4.15/all/ciao-4.15-contrib-3.tar.gz unix% wget https://cxc.cfa.harvard.edu/ciao-install/ciao-4.15/Linux/ciao-4.15.1-patch-bin-core-Linux.tar.gz unix% wget https://cxc.cfa.harvard.edu/ciao-install/ciao-4.15/Linux/ciao-4.15.1-patch-bin-sherpa-Linux.tar.gz unix% wget https://cxc.cfa.harvard.edu/cdaftp/arcftp/caldb/caldb_4.10.7_main.tar.gz unix% wget https://cxc.cfa.harvard.edu/cdaftp/arcftp/caldb/acis_bkgrnd_4.9.7.tar.gz
The following files were used to install CIAO on a 64-bit Linux (CentOS) machine:
unix% ls -1 /soft/download/ acis_bkgrnd_4.9.7.tar.gz caldb_4.10.7_main.tar.gz ciao-4.15-bin-core-Linux.tar.gz ciao-4.15-bin-obsvis-Linux.tar.gz ciao-4.15-bin-sherpa-Linux.tar.gz ciao-4.15-bin-tools-Linux.tar.gz ciao-4.15-contrib-3.tar.gz
Where should CIAO and CALDB be installed?
The CIAO software package and the Chandra Calibration Database (CALDB) can be installed in any location and do not need to be installed with root or super-user privileges.
CIAO unpacks into a directory called ciao-<version>/, i.e. ciao-4.15 for this release. If the current version of CIAO were to be installed into /usr/local/, the full path to CIAO would be /usr/local/ciao-4.15/. This directory (/usr/local/ciao-4.15/) is referred to as the root directory of CIAO in the rest of this thread. It is also the value that the $ASCDS_INSTALL environment variable is set to once CIAO has been started.
In the rest of this thread we will assume CIAO is being installed into the /soft/ directory.
CALDB may be installed in two ways:
- within the CIAO installation, in the directory $ASCDS_INSTALL/CALDB
- in a separate directory, in which case $ASCDS_INSTALL/CALDB will be a soft link to the actual CALDB location.
This thread assumes that you have installed the CALDB before starting the CIAO installation, as CIAO has to be linked to the location of those files. Installation instructions are available on the CALDB website:
Installing CIAO as the root user
It is is strongly suggested that CIAO be installed as a non-privileged, regular user and not as the root user. If CIAO must be installed in a directory owned by root and you are following the manual process, then
- create the ciao-4.15/ directory in the desired location, as the root user;
- use the chown utility to change ownership of this directory to the installer's username;
- unpack CIAO into the newly-created directory as the installer, not as the root user.
Installing the CIAO Software
1. Change to the CIAO installation directory
The CIAO 4.15.2 tarfiles create a directory named ciao-4.15 for the software installation. It is not necessary to create the CIAO directory before starting the installation.
Move to the directory in which you would like the top level of the CIAO installation to be located. If you are installing the software for a local network, this directory must also be visible to all potential CIAO users.
This thread will use the /soft directory:
unix% cd /soft/
2. Unpack CIAO 4.15.2
From the CIAO location just chosen, untar the CIAO 4.15.2 binary packages. (If you prefer more screen output, add the "v" option to the gtar command.)
unix% pwd /soft unix% gtar xzf /soft/download/ciao-4.15-bin-core-Linux.tar.gz unix% gtar xzf /soft/download/ciao-4.15-bin-obsvis-Linux.tar.gz unix% gtar xzf /soft/download/ciao-4.15-bin-sherpa-Linux.tar.gz unix% gtar xzf /soft/download/ciao-4.15-bin-tools-Linux.tar.gz
When all the files are unpacked, the CIAO directory will look like:
unix% ls -F ciao-4.15 COPYING* README.obsvis VERSION_sherpa config.sub* lib/ COPYING.LIB* VERSION VERSION_tools configure* ots/ INSTALL_BINARY VERSION.prop_tk bin/ configure.in* param/ INSTALL_SOURCE binexe/ contrib/ share/ LICENSE VERSION_core ciao-type data/ test/ LICENSE.SAO VERSION_graphics config/ doc/ Makefile VERSION_obsvis config.guess* include/ README VERSION_prism config.h.in install-sh*
3. Scripts & Modules Package
The science scripts are written and maintained by local CIAO users at the CXC. More information on each of the scripts is available from the CIAO 4.15.2 Scripts Page. Check that page for announcements about new scripts and updates to existing ones.
The tarfile is designed to be unpacked from the same directory as the CIAO software.
unix% pwd /soft/
Unpack the script tarfile:
unix% tar xzvf /soft/download/ciao-4.15-contrib-3.tar.gz ./ciao-4.15/ ./ciao-4.15/contrib/ ./ciao-4.15/contrib/Changes.CIAO_scripts ./ciao-4.15/contrib/README_CIAO_scripts ./ciao-4.15/contrib/VERSION.CIAO_scripts ./ciao-4.15/contrib/bin/ ./ciao-4.15/contrib/bin/acis_bkgrnd_lookup ... ./ciao-4.15/contrib/param/merge_obs.par ./ciao-4.15/contrib/param/specextract.par
The tarfile contains a VERSION.CIAO_scripts file. Compare the timestamp in this file to the "Last Updated" date on the Scripts page to determine when you need to update your local scripts installation.
4. Upack CIAO 4.15.2 Patch
CIAO 4.15.2 is a patch on top of the CIAO 4.15 package and must be unpacked after the base 4.15 files are unpacked. The tarfiles are designed to be unpacked from the same directory as the CIAO software. The contents of the patch tar files will overwrite the existing files.
unix% gunzip -c /soft/download/ciao-4.15.1-patch-bin-core-Linux.tar.gz | tar xf - unix% gunzip -c /soft/download/ciao-4.15.1-patch-bin-sherpa-Linux.tar.gz | tar xf -
5. Run the configuration script
Run the CIAO configuration script:
unix% cd ciao-4.15/ unix% ./configure Running CXC configure, v4.4.1 checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu checking for more... /bin/more checking for main in -lpthread... no --with-imagerdir not specified, defaulting to /soft/ciao-4.15/ots/bin configure: creating ./config.status config.status: creating bin/ciao_setup.csh config.status: creating bin/ciao_setup.sh config.status: creating ots/lib/python3.9/config-3.9m/Makefile config.status: creating bin/ciao.sh config.status: creating bin/ciao.csh config.status: creating bin/ciao.ksh config.status: creating bin/ciao.bash config.status: creating bin/setup_obsvis.sh config.status: creating bin/setup_obsvis.csh config.status: creating bin/setup_chips.sh config.status: creating bin/setup_chips.csh config.status: creating bin/setup_sherpa.sh config.status: creating bin/setup_sherpa.csh config.status: creating bin/setup_tools.sh config.status: creating bin/setup_tools.csh config.status: creating bin/ciao-python-fix config.status: creating test/smoke/bin/setup.sh config.status: creating test/Makefile
6. Run the ciao-python-fix script
Next, the ciao-python-fix script needs to be run. Despite it's name, it does more than just stuff related to python. Its runs a program that will set the location of various CIAO and off-the-shelf (OTS) libraries.
unix% bash bin/ciao-python-fix
Once this script is run, the CIAO installation cannot be moved or relocated to a different directory without repeating the configure and ciao-python-fix steps.
7. Link to CALDB
Create a link to the calibration data, changing the path to match your system installation:
unix% pwd /soft/ciao-4.15/ unix% ln -s /soft/CALDB CALDB
At this point, your directory should look like:
unix% ls -F CALDB@ README binexe/ config.sub* lib/ COPYING* README.obsvis ciao-type configure* ots/ COPYING.LIB* VERSION ciao_installed configure.in* param/ INSTALL_BINARY VERSION.prop_tk config/ contrib/ share/ INSTALL_SOURCE VERSION_core config.guess* data/ test/ LICENSE VERSION_sherpa config.h.in doc/ LICENSE.SAO VERSION_tools config.log include/ Makefile bin/ config.status* install-sh*
8. Create a CIAO alias
It is strongly suggested that you create a CIAO alias before continuing.
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-4.15/bin/ciao.csh"
bash users should add the following
to their $HOME/.bashrc file.
alias ciao="source /soft/ciao-4.15/bin/ciao.sh"
ksh users should add the following
to their $HOME/.login file.
alias ciao="source /soft/ciao-4.15/bin/ciao.sh"
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.).
Once the alias is defined, you will be able to simply type
and CIAO will be setup and ready to use in that window.
Create the Help File Indexes
In order for CIAO to be able to access the help files packaged with the software, it is necessary to create the ahelp database indexes. This step must be run by the user who owns the CIAO installation.
Start CIAO and run ahelp -r:
unix% ciao CIAO configuration is complete... CIAO 4.15 Monday, November 21, 2022 bindir : /soft/ciao-4.15/bin CALDB : 4.10.7 unix% ahelp -r Processing file '/soft/ciao-4.15/doc/xml/dmcopy.xml'...OK .... Processed Files : 1117 Succeeded Files : 1117 Failed Files : 0 Purged Duplicates: 0 Creating Key Indexes...DONE Subject DB Size: 1117 Creating Context Indexes...DONE Context DB Size: 1117 Creating Crossreference DB...DONE Crossreferences DB Size: 18181 Creating Seealso DB...DONE Seealso DB Size: 3914
Run the Smoke Tests
A set of smoke tests are packaged with CIAO 4.15.2. The tests are designed to spot-check the installation for critical problems, not to run a complete regression test of the system. The output created by the new installation of CIAO is compared against a baseline set of files included in the package.
The smoke tests include tests of a number of the GUI applications in CIAO, windows will appear and disappear during these tests. This can make using your computer difficult, since these windows may take the mouse focus or overlap your working windows.
unix% cd $ASCDS_INSTALL/test unix% pwd /soft/ciao-4.15/test
The smoke test syntax depends on the shell (tcsh, csh, bash); see this FAQ for help in determining which shell you are using.
unix% make -k test |& tee ~/ciao_test.log
bash or ksh users:
unix% make -k test 2>&1 | tee ~/ciao_test.log
The screen output provides a count of how many tests have been run:
unix% make -k test |& tee ~/ciao_test.log Requested test suite includes 40 tests [1/40] Running test prism-smoke001 .. [2/40] Running test prism-smoke002 ... PASS [3/40] Running test ahelp-smoke001 ... PASS [4/40] Running test ds9-smoke001 ... PASS ... [38/40] Running test tools-dmstat-smoke001 ... PASS [39/40] Running test tools-dmstat-smoke002 ... PASS [40/40] Running test tools-dmstat-smoke003 ... PASS All smoke tests PASSED.
Verifying test successes
A successful test is logged with a "... PASS", while an unsuccessful test reports:
[7/45] Running test <testname> ... FAIL Review /tmp/smoke.username/<testname>/diff.log for details
The smoke tests print a summary of successful and failed tests. If all tests were successful:
All smoke tests PASSED.
or if any failed:
1 out of 45 smoke tests FAILED. !! CIAO MAY HAVE FAILED TO INSTALL PROPERLY !! Please check http://cxc.harvard.edu/ciao/bugs/smoke.html for a list of known issues before contacting the Help Desk.
Run individual smoke tests
To run (or re-run) an individual smoke test you have to use the runtests Makefile target as shown here
unix% cd $ASCDS_INSTALL/test unix% make test-PACKAGE runtests
Where PACKAGE can be: ahelp, crates, dm, ds9, obsvis, sherpa, tools, or ui. For example to just re-run the sherpa smoke tests, run the following command:
unix% cd $ASCDS_INSTALL/test unix% make test-sherpa runtests Requested test suite includes 1 test [1/1] Running test sherpa-smoke001 ... PASS All smoke tests PASSED.
Test the CALDB installation
The scripts package contains a tool - check_ciao_caldb - that performs a simple check of the Chandra CALDB installation. Running the tool should produce screen output like the following:
unix% check_ciao_caldb CALDB environment variable = /soft/ciao-4.15/CALDB CALDB version = 4.10.7 release date = 2021-04-23T19:30:00 UTC CALDB query completed successfully.
For a more-thorough validation please follow the chkcif steps described on the download CALDB page.
Clean Up the Tarfiles
Finally, you may delete the tarfiles from the original download directory:
unix% rm /soft/download/ciao*tar.gz
The CIAO installation is now complete. For help getting started with the software, read the Introductory science threads.
