The GIRAFFE pipeline recipes 2.16.2 have been released!
This is a maintenance release of the GIRAFFE pipeline recipes.
Changes:
- 2.16.2 (2017-04-26):
-
- Improved version of the Reflex workflows with interactivity.
- 2.15 (2016-07-25):
-
- Reflex workflows added.
- 2.14.3 (2016-04-18):
-
- Updated to CPL 7.0.
- Maintenance release fixes missing keywords in standard (non-IDP format) products.
The distributed recipes can be used for all three observing
modes of the GIRAFFE spectrograph:
- Medusa
- IFU
- Argus
Together with the data processing modules, we also provide two standalone applications for running them:
- Gasgano, a GUI for data browsing and organisation, providing an intuitive and comprehensive interface to pipeline recipes that are based on the ESO Common Pipeline Library (CPL).
- EsoRex,
a command-line driven utility to launch pipeline recipes, which can be
used either as an interactive tool, or can be embedded into scripts for
automating some of the data reduction tasks.

Installing and running the GIRAFFE pipeline recipes
There are several ways to install the pipeline on your machine. The recommended installation procedure depends on whether you are working on a Mac OSX or on Linux.Installation using RPM repositories
For Fedora 20/21/22/23/24, it is recommended to install the pipeline from our RPM repository. The RPM repositories include not only the pipeline recipes but also the library dependencies (CPL, etc..), the Reflex workflow, demo data and the Reflex tool itself.
General installation instructions for RPM packages are provided here.
Installation using MacPorts repositories
For Apple Mac OS X 10.9 or newer, it is recommended to install the pipeline with MacPorts. The MacPorts repositories include not only the pipeline recipes but also the library dependencies (CPL, etc..), the Reflex workflow, demo data and the Reflex tool itself.
General installation instructions for MacPorts packages are provided here.
Installation using the Reflex installation procedure
Please refer to Reflex Software Prerequisites and Installation Instructions for detailed instructions
Installation using the public pipeline kit
To use the GIRAFFE pipeline recipes you will need to retrieve the pipeline distribution kit, unpack and install it.
- Prerequisites:
-
The default system C/C++ compiler for one of the OS versions listed
above, and standard GNU tools including
make
-
To use the latest graphical front-end Gasgano version 2.4.8
a Java Development Kit (JDK) version 1.8.0 or later must be available on your system. You may use either
OpenJDK, or
Oracle JDK. Most likely, OpenJDK is
already part of your Linux distribution and can be installed from its
software repositories.
The environment variable JAVA_HOME must be set correctly, and the related
java executable must be in your PATH.
Gasgano is known to be resource-intensive: see details of memory and CPU usage in Appendix A of the Gasgano User's Manual.
- Note:
-
In order to retrieve the distribution kit, you may need to configure
your Web browser so that it knows how to deal with the files we distribute,
which usually are gzip compressed tar archives (.tar.gz filename extension).
If you click on one of the links below, your browser
should display a file selection panel; if you end up instead with a page
full of strange characters, you may try clicking on the link while holding
the Shift key down, or configure your browser.
Installation procedure:
- Download the GIRAFFE pipeline kit to a directory on your computer. This may be any directory with the exception of $HOME/gasgano and $HOME/.esorex!
- GIRAFFE pipeline kit version 2.16.2 (33 MB).
-
Unpack the distribution file, using the following command:
tar -zxvf giraf-kit-2.16.2.tar.gz
-
Install: after moving into the top level directory of the unpacked
distribution,
cd giraf-kit-2.16.2
it is recommended to perform the installation using the supplied installation script:
./install_pipeline
This may take a few minutes. Please be patient!
- Note for Mac OS X users:
-
On Mac OS X the environment variable JAVA_HOME should be set to
JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home
prior to running the installation script in order to avoid compilation errors during the installation.
By default the script will install the GIRAFFE recipes, Gasgano, EsoRex, all the necessary libraries, and the static calibration tables, into a directory tree rooted at$HOME
A different path may be specified as soon as the script is run. For instance (user input is boldfaced):
$ ./install_pipeline
I am about to install the following software packages:
gasgano-2.4.8.tar.gz
cfitsio3360.tar.gz
wcslib-4.24.tar.bz2
fftw-3.3.4.tar.gz
cpl-7.0.tar.gz
esorex-3.12.3.tar.gz
giraf-2.16.2.tar.gz
- with the following pipeline calibration file(s):
giraf-calib-2.16.2.tar.gz
The software installation will be organised in bin/, lib/ and include/
directories, while the calibration files will be installed in a calib/directory.
Where should I install the software packages ? [/home/dummy] /home/dummy/pipelines
Where should I install the pipeline calibration files ? [/home/dummy/pipelines] /home/dummy/calibrations
/home/dummy/pipelines
and the static calibration tables under/home/dummy/calibrations/calib/giraf-2.16.2
The only exception to all this is the Gasgano tool, that will always be installed under the directory$HOME/gasgano
Note that the installer will move an existing$HOME/gasgano
directory to$HOME/gasgano.old
before the new Gasgano version is installed.
Important: the installation script would ensure that any existing Gasgano and EsoRex setup would be inherited into the newly installed configuration files (avoiding in this way any conflict with other installed instrument pipelines).
Alternatively, it is possible to perform a manual installation of the individual components (experienced users only): the README file located in the top installation directory contains more detailed information about a step-by-step installation.
Setup of the GIRAFFE calibration files
In order to use the GIRAFFE pipeline recipes, you may want to download additional calibration files. The GIRAFFE Standard Calibration Data Sets contain all calibrations which are necessary run the GIRAFFE pipeline immediately on scientific observations.
While these data sets are useful to get a first glance on the processed data, it is recommended to use the calibrations which have been specifically prepared for a given observation, in order to obtain the best possible results. Such calibrations may be obtained from the ESO archive using the CalSelector service.
If you decide to re-create the calibration using the GIRAFFE pipeline recipes, certain processing steps will still require some of these calibrations as an initial guess. Please check the GIRAFFE Pipeline User Manual for details.
Installing the GIRAFFE Standard Calibration Data Sets:
The latest release of the standard calibration data sets is still version 2.8.7. However, these data sets can be used together with the GIRAFFE pipeline version 2.16.2.
It is recommended to install these calibration in the same place where the static calibration tables are located and simply unpack the downloaded archive files. Continuing with the above example, you have to execute the following commands to install the calibration files for the Medusa1 fibre system:
$ cd /home/dummy/calibrations/calib/giraf-2.16.2
$ tar -zxvf giraf-data-medusa1-2.8.7.tar.gz
cal
/home/dummy/calibrations/calib/giraf-2.16.2
Using the GIRAFFE pipeline recipes
Using Gasgano
-
To run the Gasgano GUI, just add
$HOME/gasgano/bin
to yourPATH
environment variable:
export PATH="$HOME/gasgano/bin:"$PATH
You should also define an environment variableCPLDIR
to point to the same path specified for the installation. Possible files to update are:
$HOME/.bashrc
$HOME/.profile
Finally, enter the command
gasgano
-
If the Gasgano main panel appears, then you have
successfully installed Gasgano. Make sure, however, that the
expected Gasgano 2.4.8 release is running: the version number
is listed at the top of the main Gasgano panel.
-
Refer to the Gasgano User's Manual to learn how to browse
data and run pipeline recipes. Refer to the
GIRAFFE Pipeline User Manual
for detailed information about the recipes usage.
Using EsoRex
-
The EsoRex executable should be available in the
bin
directory under your installation path (see above). The$PATH
environment variable should be upgraded accordingly (similarly as done for Gasgano).
- Refer to the EsoRex web page for details about the related features and options.
