It provides a clean, simple API that exposes file headers and data as numpy arrays, making it easy to inspect, modify, and save MRC files without compiled dependencies beyond numpy itself.\n\nThe library supports gzip and bzip2 compressed files, includes validation against the MRC2014 specification, and offers memory-mapped access for efficient random access to large files. It runs on Python 2.7 and modern Python 3 versions across Linux, macOS, and Windows, and is actively maintained as part of the CCP-EM software suite used in structural biology research.","worth_installing":"Yes. mrcfile is a stable, actively maintained library with low install friction (numpy only) and no known vulnerabilities. It fills a specific, well-defined role in structural biology workflows. Install it if you work with MRC format files in cryo-EM or related fields; skip it if you have no need for MRC file I/O."},"id":"mrcfile","links":{"html":"https://skillfed.io/packages/mrcfile","md":"https://skillfed.io/packages/mrcfile.md","pypi":"https://pypi.org/project/mrcfile/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-01-22","license_spdx":null,"license_treatment":"permissive","name":"mrcfile","python_support":"unspecified","summary":"MRC file I/O library"},"popularity":{"monthly_downloads":434123,"position":6696,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.5.4"}
