Its package identity is unusually practical for structural biology: a small native library, a CLI that can process PDB/mmCIF-style inputs, and documented APIs for embedding calculations in other tools. ### Projektgeschichte The official documentation describes FreeSASA as a C library and C++ command-line tool designed to be simple with defaults while allowing detailed control of calculation parameters. It implements the Lee and Richards algorithm by default and also supports the Shrake and Rupley method. The project was presented in a 2016 F1000Research paper as an open source C library for SASA calculations with command-line and Python interfaces. Later 2.x releases split the Python bindings into a separate repository, changed parts of the C API, and added structured output formats. ### Adoptionsgeschichte FreeSASA fits the structural-biology toolchain niche where users need repeatable command-line SASA calculation without depending on older closed or narrowly distributed programs. The project's homepage explicitly targets casual users who want direct PDB-file calculation and advanced users who need C or Python APIs. The README documents installation through Homebrew and conda-forge channels as well as source builds, reflecting its adoption as both a scientist-facing command and a library package. ### Wie es verwendet wird The basic CLI workflow is to run freesasa on a PDB file with sensible defaults. More advanced use changes algorithms, atomic radii, classifications, output formats, and resolution; the library interface supports calculations directly from coordinates. Version 2.x made output and embedding more package-friendly by consolidating CLI output format selection, adding JSON and XML output options, and separating the Python module so language bindings can be released independently. ### Warum Paket-Nerds sich dafür interessieren FreeSASA is a compact example of scientific software that packages well: a C ABI, a CLI, optional JSON/XML features, man pages, Doxygen docs, and language bindings. It exposes the usual tradeoff between minimal native dependencies and richer output or parser support. Its 2.1 line added mmCIF input support using Gemmi, which matters because structural biology packaging increasingly has to handle both legacy PDB workflows and modern mmCIF data. ### Zeitleiste - 2013-2016: FreeSASA 1.1 documentation records early copyright years for Simon Mitternacht. - 2016: FreeSASA paper published describing the project as an open source C library with CLI and Python interfaces. - 2.0: Major API and CLI changes introduced JSON/XML output and a new result tree interface. - 2.0.3: Python bindings separated into the freesasa-python repository. - 2.1.0: mmCIF input support added with Gemmi. ### Related projects - freesasa-python provides the separate Python bindings repository used after the 2.0.3 split. - Gemmi is bundled as a submodule for mmCIF import in the 2.1 line. - NACCESS is a related SASA tool whose parameter set appears as a sample configuration and compatibility reference in FreeSASA documentation. ### Quellen - - - - - - - ## Sicherheitshinweise narrow executable package without higher-risk signals. - **Geiger-Risiko:** grün / niedrig - narrow executable package without higher-risk signals ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** freesasa - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Andere Paketmanager-Einträge - Debian apt - freesasa - 2.1.2-4: normalized package name match | Debian stable package indexes: freesasa from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Solvent Accessible Surface Area of biomolecules | https://freesasa.github.io - Nix - freesasa: normalized package name match | nixpkgs package indexes: pkgs/by-name/fr/freesasa/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - freesasa - 2.1.2-4: normalized package name match | Ubuntu 24.04 LTS package indexes: freesasa from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Solvent Accessible Surface Area of biomolecules | https://freesasa.github.io ## Verwandte Links - [Source-control packages](https://www.automicvault.com/de/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/de/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/de/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://www.automicvault.com/de/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [autoconf](https://www.automicvault.com/de/pkg/brew/autoconf/) - Build dependency declared by Homebrew. - [automake](https://www.automicvault.com/de/pkg/brew/automake/) - Build dependency declared by Homebrew. - [pkgconf](https://www.automicvault.com/de/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [abpoa](https://www.automicvault.com/de/pkg/brew/abpoa/) - Shares av.db curated category or tags: bioinformatics, c-library, cli, science. - [genometools](https://www.automicvault.com/de/pkg/brew/genometools/) - Shares av.db curated category or tags: bioinformatics, c-library, cli, science. - [htslib](https://www.automicvault.com/de/pkg/brew/htslib/) - Shares av.db curated category or tags: bioinformatics, c-library, cli, science. - [abricate](https://www.automicvault.com/de/pkg/brew/abricate/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [abyss](https://www.automicvault.com/de/pkg/brew/abyss/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [adapterremoval](https://www.automicvault.com/de/pkg/brew/adapterremoval/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [alevin-fry](https://www.automicvault.com/de/pkg/brew/alevin-fry/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [any2fasta](https://www.automicvault.com/de/pkg/brew/any2fasta/) - Shares av.db curated category or tags: bioinformatics, cli, science. ## Combined YAML source View the package source record on GitHub.
