mrcfile is a Python implementation of the MRC2014 file format, which is used in structural biology to store image and volume data.

It allows MRC files to be created and opened easily using a very simple API, which exposes the file’s header and data as numpy arrays. The code runs in Python 2 and 3 and is fully unit-tested.

This library aims to allow users and developers to read and write standard-compliant MRC files in Python as easily as possible with no dependencies on any compiled libraries except numpy. You can use it interactively to inspect files and correct headers for example, or in scripts and larger software packages to provide basic MRC file I/O functions.

Available in the CCP-EM suite, and via pip or conda.

The MRC image processing system includes a number of image processing tools as well as the Ximdisp display program. An overview of the system is available on the MRC-LMB website.

A pre-compiled copy of the MRC image processing system (2010) is included in the CCP-EM suite (v1). The source code for the stand-alone versions is also available here.

Installation is described in the README file. First build all the libraries and executables using a .bld file specific to your system. Binaries will then be written to image2020/bin (or image2010/bin for the older version) and all have the extension .exe

image2020 (latest version, including support for MRC mode 6 images): image2020.tar.gz
