NOC 3.0

NOC is a software application designed for protein structure visualizing and analysis, for crystallographic modelling and mapping, for Gromacs/Amber MD trajectories viewing and analysis.
NOC is an open source project and is distributed with precompiled binaries for MS Windows, MacOSX, Linux/Unix.
Main features:
- Structure factor calculation and R factor validation
- Fast fourier transformation for electron density synthesis
- Reflection data analysis
- Auto-fit residues side-chain against density data
- Customize molecular electronic density map contouring
- Easy to add/delete HOH, heteroatom Group, residue
- Real 3D Stereo Visualizing Support (need a Quad Buffer Graphic Adapter and a Stereo Glasses)
- Easy to make a animate stream of molecular model
- Solid surface creating and electrostatic potential calculation
- WYSIWYG Labeling method
- Easy to compare similar structures
- Auto structure checking and hydrogen atoms adding
- Predict possible motifs (sites) in the molecule
- Auto-determinate secondary structures
- Build related molecules and contacts according to molecular crystallographic symmetries
- Calculate molecular accessible surface, embedded surface, residue ccessibility
- Details of Heteroatom interactions in the molecule
- Details of Hydrogen bonds in the molecule
- Structure validation and quantify structure on the fly
- More precise ribbon model representation
- Novel Cartoon model representation
- Report many useful information both in text and plots for structure analysis
- High quality rendering and many types of output (such as TIFF, PNG, BMP, PS…)
