ISIS, the Interactive Spectral Interpretation System, is designed to facilitate the interpretation and analysis of high resolution X-ray spectra. It is being developed as a programmable, interactive tool for studying the physics of X-ray spectrum formation, supporting measurement and identification of spectral features, and interaction with a database of atomic structure parameters and plasma emission models.

Potential Problems

isis needs the s-lang in /usr/local/lib and cannot use the one that comes with Linux in /usr/lib. The one in /usr/lib cannot be removed with yum as it has too many system dependencies.

You should think twice before extensively googling this software.
