MIFit+

MIFit+ is a new automatic macromolecular crystal structure solution software suite. Running on both Windows^® and Linux^® platforms, MIFit+ includes the MIFit program for crystallographic model-building and the MIExpert program for running external crystallographic calculations.

MIFit is a fitting and molecular modeling program completely redesigned from the ground up to be a true cross-platform program for both LINUX and Windows. MIFit was originally written by Duncan McRee, the author of XtalView/xfit and contains all of the functionality of xfit as well as a number of new features.

MIExpert provides robust 'expert' management of crystallographic calculations including image data processing, SAD phasing, molecular replacement and refinement. MIExpert includes a pipeline process for delivering prerefined protein models and maps for co-crystal structure determination plus a tool for ligand-density docking.

Features

• MIFit reads diffraction data in CCP4 (mtz), XtalView (phs), SCALEPACK, mmCIF and d*TREK^® formats and density maps in CCP4 and xfit map formats 
• Ligand dictionary editor to set refinement restraints with data import in mmCIF, PDB, MOL, and SMILES formats 
• Built-in application for automatic ligand density docking 
• A tool for efficiently and accurately overlapping multiple ligands in a target site 
• Expert systems for: 
  • automated image data processing with d*TREK (d*TREK license included for commercial users) 
  • automatic protein:ligand structure solution ("bind and grind") 
  • molecular replacement allowing searches over multiple models and multiple space groups 
  • refinement with automatic error checking and result collection 
• Use of industry standard CCP4 and SHELX computation programs (not included) as well as proprietary fitting algorithms 
• Extensive support by our crystallographers and programmers 
• All applications run on Windows and Linux

MIFit+ is available free to academics. More information can be found at the MIFit+ distribution site.
