MIFit is a cross-platform interactive graphics application for molecular modeling, fitting, and refinement of protein structures from x-ray crystallography.

MIFit has the following features:

• Easy to navigate and manipulate multiple structures and maps.
• Improvements in graphics rendering performance.
• Customizable jobs menu for interfacing with MIExpert or your own scripts and automated systems.
• Developed with Qt 4.7 (http://qt.nokia.com).
• Cross platform – supports Windows and Linux. Building on MacOS should be possible.

Project moved to GitHub because Google Code is shutting down.

MIFit 2010.10 is available for download. See Releases. You may build MIFit yourself from the source distribution (see the enclosed README.txt), or download the Windows installer or Linux binaries archive.

MIExpert is now distributed as a separate package. Although it can be used separately, MIExpert is designed to be used with MIFit. To use MIExpert with MIFit, run MIFit and open the MIExpert/setupJobMenu.py file. The setupJobMenu.py script will configure the Job menu in MIFit. Note: MIExpert scripts require PyQt in order to run from MIFit.
