You need a Fortran compiler as f2py (now part of numpy) is used during installation to build python modules from fortran routines. If the installation fails due to a missing compiler see point 3.

1. Install Xana using pip:

   pip install Xana

2. Install Xana from github:

   git clone https://github.com/reiserm/Xana.git
   cd Xana
   pip install .

3. If a Fortran compiler is not already installed, try

   • Linux: apt install gfortran
   • MacOSX: brew install gcc
   • On Windows it is a little more complicated. A possible way to install a FORTRAN compiler is given here or here.

4. Additional remarks on the installation on OSX: if building the module fails, it might help to set the following environment variables:

   unset LDFLAGS
   unset SHELL

The Xana example has been moved to a new repository: Xana_example. It contains an example notebook and an example XPCS data set of 100nm SiO2 nanoparticles dispersed in glycerol. It shows how to create a setup file and calculate correlation functions. A detailed explanation is given in the notebook.
