leonarski_f bcb71136ab Refinement restraints: metal ions bound to their donors by the model's LINK records
Metal sites were held only by the 1.9 A metal contact of the repulsions; REFMAC restrains the metal LINKs of
the coordinate file (its documentation), which was the one geometry term the 0-cycle comparison did not
share (one 2.8 A set: bond rmsd 0.018 against REFMAC's 0.042).

- monomers/metals.cif: the Monomer Library's own statistics of metal sites (metals.json, LGPL data as the
  rest of monomers/), cut by update_monomers.py to the metal ions of its compound list and O, N, S donors:
  mean distance, spread and number of sites per metal, donor element and coordination number.
- AddMetalLinks (before prepare_topology): every LINK / struct_conn record between a metal ion and an O, N
  or S that no link of the dictionary describes (its ZN-CYS, ZN-HIS, FE-CYS, FE-HIS are taken as they are)
  gets a link of one bond at EmbeddedMetalDistance for the two elements and the ion's coordination - the
  number of its donor records, symmetry mates included - from the rows resting on at least 20 sites (the
  coordination's own row, else the neighbours interpolated), sigma their spread (>= 0.02 A); a His or Cys
  donor loses the proton the bond replaces (DEL-HD1 / DEL-HE2 / CYSmod1, as the library's links do).
  Records only, no distance search; records to a symmetry mate count for the coordination but are not
  restrained (bonds to symmetry mates are not, anywhere).
- The metal bonds are a restraint set of their own (RefinementTopology::metal_bonds), evaluated with the
  geometry and reported apart (GeometryStatistics::rmsd_metal, REFINE_RMSD_METAL_BONDS,
  REFINE_SCORE_RMSD_METAL_BONDS / _BONDS_ALL): their sigma is the spread of real sites, so they sit
  further from ideal than covalent bonds, and the weight ladder's 0.02 A bound stays a bound on the
  covalent ones. refine_parity.py compares REFMAC's bond rmsd (links included) with the combined one, and
  takes --gpu.

Score-only geometry against REFMAC 5.8 0-cycle, all bonds (count): 2.8 A Zn/Fe set 0.0402 (4934) vs 0.042
(4935), was 0.0178; a Zn-Cys set 0.0186 (7102) vs 0.019 (7102); a Ca set 0.0297 vs 0.026 (REFMAC also
refines the sugars and uses one Ca-O distance); a Mg set 0.0114 vs 0.017 (REFMAC restrains 8 symmetry
links and puts Mg-O at 1.99 A, the library's statistics at 2.07). R of the scored model unchanged (+0.0001
on the first from the removed His/Cys protons). Refined R-free with the links vs without: +0.0016, -0.0002,
+0.0005, +0.0004.
Test: RefinementRestraints_metal_links (Zn-Cys4 by the dictionary's link, Mg(H2O)6 by the new ones, both
back at their distances).

Third-party software notices

Jungfraujoch is licensed under GPL-3.0 (see LICENSE); the FPGA design is licensed under CERN-OHL-S-2.0 (see fpga/LICENSE). It builds on a number of third-party components, acknowledged below as required by their licenses.

This file is the human-readable manifest. The verbatim license texts live in the licenses/ directory (regenerate with bash licenses/COLLECT.sh). The frontend's bundled JavaScript dependencies are listed separately in frontend/dist/THIRD_PARTY_LICENSES.txt, generated at build time (npm run licenses).

All licenses below are GPL-3.0-compatible, with one exception: the NVIDIA CUDA Toolkit is used under its own EULA (see the notes at the end of this file).

Fetched at build time and statically linked into the C++ binaries

These are downloaded by CMake (FetchContent / ExternalProject) during the first configure and linked into the Jungfraujoch executables.

Mbed TLS is fetched and statically linked only for viewer builds (JFJOCH_VIEWER_BUILD / JFJOCH_VIEWER_ONLY), where it is the TLS backend of jfjoch_viewer's cpp-httplib client; the broker and writer never link it.

Catch2 is used only to build the test binary (jfjoch_test) and is not part of any shipped artifact; it is listed here for completeness.

zlib is supplied by zlib-ng built in its zlib-compatible mode (same zlib.h, same API and symbol names), so it is the zlib that HDF5, libtiff, cpp-httplib and GEMMI all link. It is built during the configure rather than added as a subproject; the licence is the zlib licence either way. Eigen is header-only: only its headers reach the binaries, and no Eigen CMake runs.

Vendored directly in the repository

These live in the source tree (see the path) rather than being fetched; traccc and the Ceres-derived minimiser are the exceptions - code adapted into first-party files rather than a vendored directory, see the notes at the end of this file.

Frontend (npm) dependencies

The React/TypeScript frontend (frontend/) bundles a large transitive tree of npm packages, overwhelmingly MIT/ISC/BSD/Apache-2.0 licensed. Their full notices are generated automatically:

cd frontend && npm run licenses     # writes dist/THIRD_PARTY_LICENSES.txt

The generated file is produced as part of the frontend build target and installed alongside the served frontend, so the shipped web UI carries its own attribution.

Notes on weak-copyleft and attribution-sensitive components

  • MPL-2.0 (Eigen, GEMMI, libzmq, traccc): file-level copyleft. GEMMI is vendored in gemmi_gph/ in trimmed form; libzmq and Eigen are fetched at build time (Eigen is header-only). The corresponding source is available from each project upstream.
  • GEMMI's own bundled third-party headers — PEGTL, sajson, fast_float, half, pocketfft and tinydir, all under gemmi_gph/gemmi/third_party/ — are listed separately above rather than being absorbed into GEMMI's row: they are other authors' code under other licences (MIT, BSD and Apache/MIT/BSL), and GEMMI's MPL-2.0 does not speak for them. Their terms are carried in the headers themselves rather than in LICENSE files, so the licenses/*.txt copies are kept by hand; only PEGTL ships a LICENSE, which COLLECT.sh copies.
  • traccc is the one entry that is not a vendored directory. Its sparse connected-component labelling enters two otherwise first-party files: StrongPixelSet.cpp adapts the SparseCCL source, and SpotExtractorGPU.cu follows the design of its GPU counterpart. MPL-2.0 is file-level, so both files name the origin at the top and are covered by licenses/traccc.txt. See ACKNOWLEDGEMENT.md for the citation.
  • Ceres Solver is also fetched and linked (table above); separately, LMSolver.h/.cpp re-implement its trust-region Levenberg-Marquardt minimiser, projected line search, polynomial step choice and sphere manifold for the crystal refinement, following its source. Both files name the origin at the top and are covered by licenses/ceres-solver.txt.
  • fast-feedback-indexer is also vendored and linked in CUDA builds (table above); separately, FFBIDXIndexerCPU.cpp ports its CUDA kernels to the CPU. The file names the origin at the top and is covered by licenses/fast-feedback-indexer.txt.
  • FFTW is GPL-2.0-or-later — compatible with, and absorbed by, this project's GPL-3.0 license.
  • Apache-2.0 components: where upstream ships a NOTICE file, it is reproduced in the corresponding licenses/ text.
  • CCP4 Monomer Library (LGPL-3.0) is data, not code: the restraint dictionaries of the compounds rugnux's refinement restrains, copied unmodified per compound into image_analysis/structure_refinement/monomers/ (links_and_mods.cif and ener_lib.cif cut down to the entries those compounds use, and the library's metal-site distances of metals.json for its ions as metals.cif), with the library's own COPYING. The build embeds them in the binary as text, and monomers/update_monomers.py regenerates the subset from the upstream library, so the copy can be replaced by a user with a version of their own.
  • Qt (LGPL-3.0) and NVIDIA CUDA (EULA) carry redistribution conditions beyond a copyright notice; see their dedicated notice files. The verbatim LGPL-3.0 and CUDA EULA texts are bundled (licenses/Qt6-LGPL-3.0.txt, licenses/NVIDIA-CUDA-EULA.txt); the CUDA EULA is the one shipped with CUDA Toolkit 12.8 — replace it if you build against a different toolkit version.
