Dependencies

The following packages need to be installed before using relax:

Python:

Version 2.5 or higher.

NumPy:

Version 1.6 or higher. This package is used for most of the numerical calculations within relax.

SciPy:

Version 0.7.1 or higher. This package is optional. It is required only for the frame order theory analyses.

wxPython:

Version 2.9 or higher. This package is also optional. It is required for the operation of the graphical user interface (GUI).

mpi4py:

Version 1.2 or higher. This optional dependency is essential for running relax in MPI multi-processor mode.

Older versions of these packages may work, use them at your own risk. If, for older dependency versions, errors do occur please submit a bug report to the bug tracker. That way a solution may be created for the next relax release.

Note that only the official Python distribution from http://python.org is supported. If you use the Enthought Python Distribution (EPD) or other non-official distributions you may encounter problems with the relax C modules, the graphical user interface, or other issues. These alternative distributions are to be used at your own risk. Any issues encountered will not be considered as relax bugs.
