CueMol – Free Tool to Macromolecular Structure Visualization

CueMol is a free computer program for the macromolecular structure visualization. It aims to visualize the crystallographic models of macromolecules with the user-friendly interfaces. Currently supported files are molecular coordinates (PDB format), electron density (CCP4, CNS , and BRIX formats), MSMS surface data, and APBS electrostatic potential map.

Main functions

Display proteins and nucleic acids
Supported input format is PDB (molecular coordinates).

• simple stick model
• main-chain trace (Calpha backbone, phosphate backbone, …)
• ball-and-stick model
• CPK model

Functions as a molecular viewer

• [advt]Residue selection by clicking
• Residue selection by chain and residue numbers
• Change or create new display for the selected residues
• Display symmetric molecules
• Display unit cell
• Hardware stereo support
• Display the distance between atoms
• Dump/restore the current state to/from the file (workspace)

Display electron-density maps
Supported input formats are CCP4 (type2), X-PLOR/CNS (ascii), and BRIX

• Mesh and surface display of electron-density maps (you can change the contour level dynamically!!)
• Display electron density of an arbitrary (cubic) region.
• Geometric object (solid/dashed lines)
• Molecular surface object (generated by MSMS program)
