HDTV - Nuclear Spectrum Analysis

HDTV is a nuclear spectrum and coincidence matrix analysis tool. It can load uncompressed (text), compressed, and ROOT spectra and 2D-matrices. It calibrates spectra, fits peaks with background with different models, and cuts matrices. HDTV is written in a mixture of C++ and Python, glued together using PyROOT.

Installation

HDTV requires CERN ROOT with working Python bindings.

pip install hdtv

If pip raises error: externally-managed-environment, you can install hdtv in a virtual environment, for example by using pipx:

pipx install hdtv --system-site-packages

If you use hdtv with a location-independent ROOT installation (i.e., you have to source <...>/thisroot.sh, e.g. in .bashrc or manually), you can leave out the --system-site-packages option.

Please note that the python package (wheel) does currently not include the compiled libraries required to run, as these depend on the root version, the python version, the compiler, and the moon phases. Instead, these are compiled automatically at first start, which requires certain build tools (see below).

Alternatively, the compilation can be triggered with

hdtv --rebuild-usr

for the current user; or with

hdtv --rebuild-sys

for all user (requires superuser privileges).

Requirements

To build and run HDTV, the following dependencies are required:

• Python
  • Tested with 3.9, 3.10, 3.11, and 3.12
  • Python-dependencies are installed automatically when using pip/pipx
    • Packages: numpy scipy matplotlib prompt_toolkit>=3.0.14 uncertainties (when manually installed)
    • Packages for development & testing: docutils pytest pytest-cov
• Cern ROOT 6
  • Tested with version 6.26 and higher
  • Needs to be compiled against the correct python version and with support for C++14 or higher.
  • In python, import ROOT must succeed.
  • System packages may be available on some systems, e.g. <tool> install root python3-root (More info)
• cmake, gcc, g++ (or similar, in a somewhat modern version)
• libx11-dev <tool> install libx11-6 libx11-dev

Usage with docker

With docker installed, build the image with:

git clone https://github.com/janmayer/hdtv.git
cd hdtv
docker build --tag hdtv .

On Linux and MacOS, no further installation is required and in the directory with your project you will be able to use HDTV with:

docker run -e DISPLAY=${DISPLAY} -v /tmp/.X11-unix:/tmp/.X11-unix -v $(pwd):/work -it hdtv

When using SELinux, the additional argument --security-opt label=type:container_runtime_t is required (before -it).

On Windows, you will need to have an X-Server installed, for example with MobaXTerm, and be a bit more specific:

docker run -e DISPLAY=<your ip>:0.0 -v <full path to your files>:/work -it hdtv

e.g. docker run -e DISPLAY=192.168.178.21:0.0 -v D:\Project\Spectra:/work -it hdtv.

Documentation

For more information, including an overview of the available key bindings, refer to the documentation. A tutorial giving an introduction to HDTV and its basic features is also available.

Further installation topics

Run locally from source directory without installation

git clone https://github.com/janmayer/hdtv.git
cd hdtv
./bin/hdtv

Generate man pages:

cd doc/guide
make doc

Handling different ROOT versions

HDTV uses ROOT.gSystem.Load(libary) to load some critical components. These need to be compiled against the exact ROOT version imported in python. HDTV will try to automatically recompile the libraries for the current ROOT if the available ones cannot be loaded. This can also be forced with:

hdtv --rebuild-usr

When installed system-wide, the libraries can be recompiled once for all users with:

hdtv --rebuild-sys

This eliminates the need to reinstall HDTV after changes to the root installation.

Multiple Versions of ROOT can be used alongside, the correct library version will be chosen automatically.
