# Getting Started

This page provides information to assist users when processing data obtained with the Gemini telescopes. Please see the requirements page for information relating to installing the Gemini IRAF package. For those new to IRAF, general IRAF documentation is available. In addition, a presentation called An Introduction to IRAF and the Gemini IRAF package was given at the 2014 AusGO/AAO Observational Techniques Workshop in Sydney, Australia, in conjunction with an interactive Python / PyRAF demonstration in the form of an IPython notebook (to run the IPython notebook, type **ipython notebook** in the directory where the IPython notebook is located then go to your browser). For instrument specific information, please follow the links below.

__GPI__

The GPI instrument builders and incidentally the campaign team has developed a powerful data reduction tool in IDL. At least for the duration of the GPI campaign, the software is maintained and developed by the campaign team.

The software and the documentation can be obtained at:

http://docs.planetimager.org/pipeline

The GPI campaign team is providing a "source package" which contains all the source code and requires the user to have an IDL license to run the software. **However**, they also provide a "runtime package" both for Linux and Mac OS X that has compiled code and includes the IDL runtime library that can be run for free without a license. If you do not have an IDL license, use that second type of package.

All the tools are GUI-based. You do not need to know IDL.

A series of papers detailing GPI data and its analysis can be found in the GPI documents section
