If you do not have an IDL license, the GPI Data Reduction Pipeline is distributed as compiled code along with the IDL runtime.
Note
If you do have an IDL license, there’s nothing stopping you from installing these compiled versions of the code instead of the source if you want to; it’s just not required!
The distribution ZIP files for the GPI pipeline come in two flavors:
- A platform-independent ZIP file containing only the compiled pipeline code itself. To use this file, you must download and install the IDL runtime virtual machine yourself. It may be obtained from Excelis.
- Platform specific ZIP files that contain the compiled pipeline code plus the IDL runtime virtual machine for a given operating system. These contain everything you will need to start the GPI pipeline on that OS.
Obtain the desired zip file and uncompress it to a directory of your choosing. Remember this path for use when configuring DRP paths in the next section.
The zip file contains, among other things, a directory called executables which contains .sav files needed by the Virtual Machine to run the pipeline:
- gpi_launch_pipeline.sav starts the main data reduction session and status console
- gpi_launch_guis.sav starts the GUI session, including a launcher window that will allow the user to start the various GUIs.
- gpitv.sav starts GPItv alone.
How to start the compiled code varies by operating system.
Mac OS X
On Mac OS X, the executables directory contains three Applescript files corresponding to the above named .sav files. Double click any of these to start that component of the pipeline. You can also start compiled code from the command line
unix% idl -rt=/path/to/executables/gpi_launch_pipeline.sav
To conveniently start both required IDL sessions at once, there is a shell script scripts/gpi-pipeline which launches two xterms and starts the pipeline and GUIs sessions in them.
You may need to set the environment variable IDL_DIR to the executables\idl## directory.
Linux
You can start compiled code from the command line
unix% idl -rt=/path/to/executables/gpi_launch_pipeline.sav
To conveniently start both required IDL sessions at once, there is a shell script scripts/gpi-pipeline which launches two xterms and starts the pipeline and GUIs sessions in them.
You may need to set the environment variable IDL_DIR to the executables\idl## directory.
Windows
On Windows, the executables directory contains three .exe files corresponding to the above named .sav files. Double click any of these to start that component of the pipeline.
You must manually start both the pipeline and GUIs sessions to use the pipeline interactively.
For any of the above OSes, you may also manually start the IDL Virtual Machine by itself, and it will present you with a file dialog for browsing to and selecting a .sav file to run. See the Exelis documentation on starting a runtime application for more information.
If you have followed these steps successfully, you have installed the pipeline code. Proceed now to Configuring the Pipeline.
