DebiChem Molecular mechanics packages

Adun is a biomolecular simulator that also includes data management and analysis capabilities. It was developed at the Computational Biophysics and Biochemistry Laboratory, a part of the Research Unit on Biomedical Informatics of the UPF.

Avogadro is a molecular graphics and modelling system targeted at molecules and biomolecules. It can visualize properties like molecular orbitals or electrostatic potentials and features an intuitive molecular builder.

Features include:

• Molecular modeller with automatic force-field based geometry optimization
• Molecular Mechanics including constraints and conformer searches
• Visualization of molecular orbitals and general isosurfaces
• Visualization of vibrations and plotting of vibrational spectra
• Support for crystallographic unit cells
• Input generation for the Gaussian, GAMESS and MOLPRO quantum chemistry packages
• Flexible plugin architecture and Python scripting

File formats Avogadro can read include PDB, XYZ, CML, CIF, Molden, as well as Gaussian, GAMESS and MOLPRO output.

Ghemical은 C++로 작성된 계산 화학 소프트웨어 패키지입니다. Ghemical은 그래 피컬 사용자 인터페이스를 가지고 있으며, 양자 역학 (반경험적) 모델과 분자 역 학 모델 양쪽을 모두 지원합니다. 구조 최적화, 분자 동력학 그리고 OpenGL을 사 용하는 여러가지 시각화 도구등이 현재 사용할 수 있습니다.

Ghemical은 양자 역학 계산을 제공하는 외부 코드에 의존합니다. 반경험적 방법 MNDO, MINDO/3, AM1 그리고 PM3은 MoPAC7 (퍼블릭 도메인)패키지에서 가져왔으 며, 이 패키지에 포함되어 있습니다. MPQC 패키지는 순이론 방법을 제공하기 위 해서 사용되고 있습니다: Hartree-Fock 이론에 근거한 이 방법은 현재 STO-3G 에 서 6-31G** 까지 범위를 기본 세트로 함께 지원됩니다.

GROMACS is a versatile package to perform molecular dynamics, i.e. simulate the Newtonian equations of motion for systems with hundreds to millions of particles.

It is primarily designed for biochemical molecules like proteins and lipids that have a lot of complicated bonded interactions, but since GROMACS is extremely fast at calculating the nonbonded interactions (that usually dominate simulations) many groups are also using it for research on non- biological systems, e.g. polymers.

LAMMPS is a classical molecular dynamics code, and an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator.

LAMMPS has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grained or mesoscopic systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the atomic, meso, or continuum scale.

LAMMPS runs on single processors or in parallel using message-passing techniques and a spatial-decomposition of the simulation domain. The code is designed to be easy to modify or extend with new functionality.

VOTCA is a software package which focuses on the analysis of molecular dynamics data, the development of systematic coarse-graining techniques as well as methods used for simulating microscopic charge transport in disordered semiconductors.

csg is Votca's coarse-graining engine.

VMD stands for Visual Molecular Dynamics. While text books and even structure databases because of technical problems only present static pictures of proteins or DNA, for the understanding of the properties of those molecules their vibration or their movement in general is important.

The movements itself are calculated by molecular dynamics programs, such as NAMD (by the same group), Rosetta, BALLView or GROMACS. The latter two are already in the distribution, we have package build instructions for Rosetta.

VMD has a series of nice features, from displaying through animation to analysing. It can be scripted, clustered, and runs on all common OS. Its license does not allow to redistribute a Debian package. But to share these build instructions for such a package is just fine.
