Getting started with SPEX has become easier because of the development of new guides and manuals. Please check out the new SPEX cookbook, and Examples and Exercises below.

If you need only a Quick Start Guide, we offer a brief introduction here.

Tip: You can search our manuals also using Google. Just type ' spex <search>' in the Google search bar with <search> replaced by the text you want to search for. Our HTML manuals are online since August 2015 and should get higher in the Google index if they are used more often.

Examples and exercises

We provide several exercises that can be used to learn how to fit a spectrum with the SPEX software. The PDF file below contains the description of the exercises and "Exercise files" contains all the spectra en response files that are needed to complete the exercises.



The data can be extracted from the TAR archive using the following command:

tar xvfz exercise-files.tar.gz  

User model examples

In the SPEX cookbook we describe how to use the new 'user' model in SPEX. Users can now create their own executable to calculate either an additive or multiplicative model. We provide a tar file with some example files in Python and Fortran 90 (we hope to extend this soon) here:


We also started maintaining a SPEX github page with additional tools and example user models.
