It provides a programmatic interface to parse and manipulate these file formats, which encode structural and modeling metadata for complex biological systems. The package includes an optional C extension for faster file I/O, but falls back to pure Python if a C compiler is unavailable during installation.\n\nThe library is designed for researchers working with integrative structural biology data, particularly those using the IHM framework for modeling multi-component complexes. It depends on msgpack for BinaryCIF support and integrates with the broader ecosystem of structural biology tools. The package is actively maintained and has been in use since 2018.","worth_installing":"Yes, if you work with integrative/hybrid modeling data in structural biology. The package is actively maintained, has no known vulnerabilities, and is permissively licensed. Install friction is moderate\u2014pip will attempt to build a C extension (requiring a compiler), but the library degrades gracefully to pure Python if compilation fails. For non-IHM structural models, consider python-modelcif instead."},"id":"ihm","links":{"html":"https://skillfed.io/packages/ihm","md":"https://skillfed.io/packages/ihm.md","pypi":"https://pypi.org/project/ihm/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-06-05","license_spdx":null,"license_treatment":"permissive","name":"ihm","python_support":"unspecified","summary":"Package for handling IHM mmCIF and BinaryCIF files"},"popularity":{"monthly_downloads":159732,"position":10689,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.11"}
