CCP4 Install

CCP-EM uses programs from CCP4 for a number of tasks. To use those tasks, please install CCP4 from and activate it before running CCP-EM.

CCP-EM is developed with the latest update of CCP4. Older CCP4 versions failed with larger EM maps (affecting Refmac and LocScale) so please ensure you use the current version (you can manage updates via the CCP4 update manager - run ccp4um).

Modeller Install

FlexEM and some other programs require Modeller to be installed and for users to have obtained a valid licence key. Please register for a Modeller licence key (free for academic use).

Linux: After running ./ you will be prompted to run ./ Please run this and enter the license key when prompted.

Mac: Please download and install the Modeller Mac package and use default installation location.


MpUL-multi: Software for Calculation of Amyloid Fibril Mass per Unit Length from TB-TEM Images.

Astbury Centre for Structural Molecular Biology, Leeds, UK.

MpUL-multi is a program for calculating the mass per unit length (MPL) of amyloid fibrils from dark field imaging, by comparing to a standard of known MPL. A graphical user interface allows for simple designation of fibrils and standards. A second program averages intensities from multiple TMV molecules for accurate standard determination, makes multiple measurements along a given fibril, and calculates the MPL. The software is written in Python, and requires a local installation of FIJI or ImageJ. Download and unpack this file, and follow the instructions in README.txt.

A paper describing the approach has been submitted.

TVIPS tools for electron diffraction

The tiff2smv and tvips2smv utilities convert sequences of related electron diffraction images, or sweeps, recorded by Tietz Video and Image Processing Systems (TVIPS) cameras to the Super Marty View (SMV) format. Output SMV images are directly suitable for further processing in suites such as MOSFLM or XDS. tiff2smv supports TIFF images written by either EMMENU or EM_Player, as long as their pixel intensities can be losslessly represented as 16-bit unsigned integers. tvips2smv supports all TVIPS set files written by EMMENU.

Availability: The software is copyright Howard Hughes Medical Institute, and made available under a permissive Internet Software Consortium license.

Shape Matching for Structural Biology (SMaSB)

The SMaSB software package has been developed to perform volume matching between a query volume and another volume or set of volumes. The primary aim is to search for similar volumes, rather than to optimise a particular fit. The software is primarily a set of Python codes, and has been extensively tested in Ubuntu 12.04 and Mac.

Software for Particle Picking - Alan Roseman

The following software is written by Alan Roseman's group at the University of Manchester, UK. The software is distributed under GPLv3. If you download/use the software, please send the author a quick email - improvements to the software depend on future funding which depends on measureable impact!

Software for 3D reconstruction of tip complexes - Ariel Blocker

These 2 packages are hosted by CCPEM on behalf of Ariel Blocker (, and are the data and scripts used in Cheung et al. (2014).

T3SS_TC 3D Reconstruction
Package of programs, instructions and test data (T3SS needle tips) to reconstruct in 3D an asymmetric complex at the tip of a filament of known helical symmetry.
The GhostBuster procedure is a package of scripts, instructions, and test data (T3SS needle tips) that implements a method to improve the azimuthal alignment of particles derived from a 3D reconstruction from the T3SS reconstruction above (T3SS_TC 3D reconstruction).

MRC Image Processing System - Tony Crowther, Richard Henderson & Jude Short (Smith)

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 is included in the CCP-EM suite. The source code for the stand-alone version is also available here.

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