KM3NeT TestData

A hybrid Python/Julia package to get access to KM3NeT sample files for testing and development purposes.

Installation and usage

Python

pip install km3net-testdata

The file paths can be access in Python scripts using the data_path() function:

from km3net_testdata import data_path

filename = data_path("offline/km3net_offline.root")

Notice the underscore in the Python package name (PyPI forces - but Python package names are not allowed to use -).

Julia

Make sure the "KM3NeT Julia Registry" is added to your local Julia registries, see https://git.km3net.de/common/julia-registry for more information. The Julia package is called KM3NeTTestData and can be installed the usual way:

julia> import Pkg; Pkg.add("KM3NeTTestData")

The package exports the datapath() function which can be used similar to the Python implementation:

julia> using KM3NeTTestData

julia> filename = datapath("offline", "km3net_offline.root")
"/Users/tamasgal/.julia/packages/KM3NeTTestData/zb9oT/src/../km3net_testdata/data/offline/km3net_offline.root"

Shell

To use the Python module in e.g. shell scripts, it can be called directly to print the filepath:

$ python -m km3net_testdata offline/km3net_offline.root
/full/path/to/offline/km3net_offline.root

It can be combined with other shell tools, as usual:

$ head -n 5 $(python -m km3net_testdata detx/detx_v3.detx)
# a comment line
# another comment line starting with '#'
