Downloading CIAO 4.7
The ciao-install script is designed to simplify and automate the installation and upgrade of CIAO and the Chandra Calibration DataBase (CALDB). ciao-install FTPs the selected files to your computer, verifies them via md5sum, and unpacks them. The script configures CIAO, sets up the command-line ahelp system, and (optionally) runs the CIAO smoke tests.
The ciao-install.README file has detailed information on the script. For a summary of options, run the script with the "-help" option.
Known issues are listed on the Installation & Smoke Tests bug page.
(1 Oct 2015) CIAO 4.7 does not work with Apple's OS X 10.11: El Capitan. While some individual tools and applications may work, many of the Python and Shell based applications and contributed scripts do not.
(20 Oct 2015) ChIPS in CIAO 4.7 is incompatible with XQuartz 2.7.8. Users must use version 2.7.7 or earlier.
CIAO 4.7 will be the last CIAO release that will be available for 32bit Linux and OSX 10.6.8/10.7.
Users are encouraged plan ahead for 2015 if still using any of these operating systems.
This method allows ciao-install to determine what platform you are using, then downloads and installs the standard CIAO installation: CIAO tools, ChIPS, Sherpa, the main CALDB tarfile, and the science scripts.
This method may also be used to download and install software patches, calibration releases, and science script updates.
- Check the supported platforms page for the machine you are running on.
Run the script:
unix% bash /<path>/ciao-install
- Check for smoke test results for errors. Known issues are listed on the Installation & Smoke Tests bug page.
CIAO and the full CALDB (excluding background files) require 3 GB of disk space to download the tarfiles and 9.05 GB to install the software and calibration files. Upgrading an existing CALDB requires about 70% less disk space for the tarfile.
For detailed instructions, refer to the ciao-install thread page.
Step 4: Check smoke test results
Users are strongly encouraged to run the CIAO smoke tests. They only take a few minutes to run and will immediately highlight any system incompatibilities before you get too deep into your analysis.
There are some known failures and workarounds for certain platforms. as listed on the Installation & Smoke Tests bug page.
