Tdl Installation

Notes

Tdl includes a number of application modules, binary libraries and utilities. Tdl can be installed as a python package and used from the python shell, from within other python packages or scripts, or as a standalone program (using the pds interpreter). If you want to download a standalone version of tdl/pds built for windows check here. You can browse the source code here

Dependencies and packages

If you do not have these packages installed locally follow the provided links to install them. Usually most recent is best with some noted exceptions. The following are required for tdl: Python (2.6 or higher), [Numpy] (http://numpy.scipy.org/), [Scipy] (http://www.scipy.org/Download), [Matplotlib] (http://matplotlib.sourceforge.net/), [H5py] (http://code.google.com/p/h5py/downloads/list), and Python Imaging Library

If you want to run the graphical user interface of pds you'll need wxPython (get unicode version) , and pythoncard

To use the reflectivity module currently you will need to have Ifeffit installed and have the Ifeffit python library installed in your PYTHONPATH You'll might also need the Ifeffit environment variables defined. See XX for more info.

The following arent required, but you might find useful: PyTables python hdf interface (also check out ViTables ) for viewing hdf files, Pyreadline, and pywin32 modules for windows users

After installing python and associated packages, make sure the python installation directory on your systems 'PATH' so that >>python works from your command line

Grab the source code

  • You can download a recent source tarball (or zipfile) from the download page

  • Or you can download the most recent source using git: >>git clone http://github.com/xraypy/xraylarch.git

  • Install into your site-packages using: >>python setup.py install

  • To access the scripts make sure the .../python/../site-packages/tdl/scripts directory is on your system PATH

Working with the development version

If you want to keep the tdl package in a non-standard location (e.g. in your home directory) just make sure to the root directory to your PYTHONPATH. For example if you put tdl under /home/user/bob/devel/tdl, add PYTHONPATH=/home/user/bob/devel to your environment variables.

Startup

  • To test your installation try the following: \>>python python>>from tdl.pds import runpds python>>runpds.main()

  • If the tdl/scripts directory is on your PATH then the following should also work >>pds
