The APPLGrids used to generate these sets can be found here:
Clone the master development repository by running the following command:
$ git clone https://github.com/scarrazza/smpdf.git
Or download the compressed archive without using git here.
$ lhapdf-config $ applgrid-config ``` The default Applgrid installation **will not work**: **All** header files must be copied to the appromiate include path, and not only those copied by `make install`, which is insufficient. For example, for a default Ubuntu installation: ````Shell applgrid-1.4.70/src $ sudo cp *.h /usr/local/include/appl_grid/
Python 3.4+ is also required.
In order to manage the Python dependencies,
Anaconda (with a Python
3.4+ environment) is the recommended way. After setting it up, cd into the directory of SMPDF and:
$ conda install --file environment.yml ``` Once all dependencies are satisfied, run: ````Shell $ python setup.py install ``` Note that the installer script does _not_ check for dependencies. This will install the `smpdf` program and the `smpdflib` Python library in the appropiate paths. ## Usage The configuration is specified in YAML files (see `examples/`). A file consists of a list of observables (file paths to applgrids and specification of the perturbative order, where 0 is LO and 1 NLO), a list of PDF sets (valid LHAPDF grids in the correct path) and a list of actions (see `--help` for a description). See ````Shell $ smpdf --help ``` for the full list of options. Note that you will probably want to run with the `--use-db` flag. Generating documentation ------------------------ [Sphinx](http://sphinx-doc.org/) version 1.3.1 or greater is required. In order to build the documentation, go into the `docs` directory, and type: ````bash make api make html
You can use the other build targets allowed by Sphinx. Note that the
--help flag provides an overview of the most useful options.
