Mac OS X Applications A-C
Aabel :- Data Analysis
Abinit :- Density Functional Theory
ADF2006 :- Density Functional Theory
Both programs support all elements in the periodic table, can include spin-orbit coupling self-consistently, offer a broad range of spectroscopic properties, and are popular for structure and reactivity, as well as chemical analysis studies. The post-ADF COSMO-RS module predicts thermodynamic properties of mixed fluids.
Graphical interfaces make the codes easy to learn and use, and are supported on all major computer platforms (Windows, Mac, Linux, UNIX).
The codes use linear scaling techniques and scale well in parallel, so you can handle large molecules and unit cells.
A brief summary of new features:
* Spectroscopy: excited state gradients, Franck-Condon vibronic effects, (resonance) VROA, selected range of excitations, NMR for solids
* Solvation effects: COSMO for periodic structures, 3D-RISM in ADF
* COSMO-RS database: 1800 precalculated standard solvents for fast thermodynamic property calculations
* Studying Potential Energy Surfaces: TSRC transition state search, ADIIS SCF convergence method, improved delocalized optimizer, Grimme's DFT-D3 dispersion corrected xc functionals
* Efficiency: various speed ups in BAND, shared-memory library enables jobs previously limited by the memory per core

AIMAII:- package for performing quantitative and visual QTAIM
AIMAll is a software package for performing quantitative and visual QTAIM (Quantum Theory of Atoms in Molecules) analyses of molecular systems - starting from molecular wavefunction data. Two of AIMAll's components (AIMExt and AIMInt) are very heavily modified and extended derivatives of two programs (Extreme and ProaimV) from the AIMPAC package that was developed and maintained by members of Richard F.W. Bader's research group. The initial goal for AIMAll was to make a QTAIM package that was:
- Easy to use, essentially automatic
- Relatively fast and efficient
- Able to calculate a rich variety of properties of interest
- Able to produce a descriptive consolidation of all important results
Once this goal was reasonably close to being achieved, work on AIMAll accelerated, including extensive work on a visualization component (AIMStudio) and shared memory multi-processor support for AIMAll calculations. Visualization and shared memory multi-processor support have recently been added to the AIMAll package. These features require an AIMAll Professional license in order to be used with non-small wavefunctions. AIMAll is actively developed to address any issues which may arise, to expand upon existing features and algorithms and to implement new features and algorithms. AIMAll is available for Windows, Mac OS X and Linux.

AMBIT :-Chemoinformatics system
The full AMBIT data management system has a modular structure and is implemented in two versions: stand-alone and web-based (http://ambit.acad.bg ). It is written in Java to be platform independent and its cheminformatics functionality relies on the open source Java library – The Chemistry Development Kit. The database uses the MySQLdatabase, an open source relational database for speed and convenient access to disparate data sources. The chemical structures are stored in Chemical Markup Language (CML) the acknowledged method of encoding chemical data in XML. The choice of CML as the internal format makes the database independent of the software that is able to access it. Whilst it has not been tested on Mac OS X the developers would be very keen to hear about peoples experiences and seem very responsive.

|Oleg Trott, Arthur J. Olson|
|Department of Molecular Biology, The Scripps Research Institute, La Jolla, California|
|AutoDock Vina, a new program for molecular docking and virtual screening, is presented. AutoDock Vina achieves an approximately two orders of magnitude speed-up compared with the molecular docking software previously developed in our lab (AutoDock 4), while also significantly improving the accuracy of the binding mode predictions, judging by our tests on the training set used in AutoDock 4 development. Further speed-up is achieved from parallelism, by using multithreading on multicore machines. AutoDock Vina automatically calculates the grid maps and clusters the results in a way transparent to the user|

CFOUR:- Coupled-Cluster techniques for Computational Chemistry
CFOUR (Coupled-Cluster techniques for Computational Chemistry) is a program package for performing high-level quantum chemical calculations on atoms and molecules. The major strength of the program suite is its rather sophisticated arsenal of high-level ab initio methods for the calculation of atomic and molecular properties. Virtually all approaches based on Møller-Plesset (MP) perturbation theory and the coupled-cluster approximation (CC) are available; most of these have complementary analytic derivative approaches within the package as well. Studies of excited electronic states and other "multireference" problems are possible using the equation-of-motion (EOM) coupled-cluster techniques. These techniques which are closely related to (and in some cases identical to) so-called Fock space multireference coupled-cluster theory, offer a powerful means to study open-shell systems and decided advantages when configuration mixing is important. At present, these include the EOMEE approach for singlet and triplet excited states, and the EOMIP and EOMEA methods that are best applied to low-spin doublet states. Analytic derivatives are available for these methods. A number of methodological developments have been added to the program in the last two decades. These include: analytic second derivatives for all coupled-cluster approaches up to full CCSDT; the calculation of NMR chemical shifts at MP and CC levels of theory; the calculation of anharmonic force fields (via numerical differentation of analytic derivatives); relativistic corrections; corrections to the Born-Oppenheimer approximation at the CC level; nonadiabatic coupling within the EOM framework, and several others.
Ch :- Programming
C is for low-level system programming and embedded systems; C++ for large-scale projects; Ch for platform-independent script computing. C/Ch/C++ allow users to use one language, anywhere and everywhere, for any programming tasks
Checkmol/Matchmol :- Molecular functional group analysis
Another output option of checkmol is a set of statistical values derived from a given molecule, which can also be used for quick retrieval from a database. These values include: the number of atoms, bonds, and rings, the number of differently hybridized carbon, oxgen, and nitrogen atoms, the number of C=O double bonds, the number of rings of different sizes, the number of rings containing nitrogen, oxygen, sulfur, the number of aromatic rings, the number of heterocyclic rings, etc. The combination of all of these values for a given molecule represents some kind of "fingerprint" which is useful for rapid pre-selection in a database structure/substructure search prior to a full atom-by-atom match (see below).
Matchmol complements the capabilities of checkmol. It compares two (or more) molecular structures and determines whether one of them is a substructure of the other one. This is done by a full atom-by-atom comparison of the input structures. Thus, matchmol can be used as a back-end program for structure/substructure search operations in chemical database.
Note: if you are running MacOS X, use the following command:

CHil2 :- Molecular modelling
GlamDock, is a docking tool, has recently been validated on two benchmark datasets (see publications). On the smaller benchmark, on which data for other docking tools is available, GlamDock was shown to perform better than the best established docking tools (62% scoring accuracy compared to 57% for the best contender Gold, Glide 55%). GlamDock is based on a Monte-Carlo with minimization (basin hopping) search in a hybrid interaction matching / internal coordinate search space. GlamDock is highly efficient, taking from 5 seconds (fast virtual screening settings) to ~20 seconds (high quality docking settings) on average on standard 2.8GHz Intel Xeon CPUs. Newest developments include an improved scoring function for pose recognition and virtual screening, and the introduction of protein flexibility into GlamDock. In cooperation with our partners GlamDock has been integrated in a de novo molecular design strategy.
Graph based Molecular Alignment (GMA) is a combined 2D/3D approach for the fast superposition of flexible chemical structures, which is based on recent progress in the efficient identification of common subgraphs and a gradient-based torsion space optimization algorithm. The simplicity of the approach is reflected in its generality and computational efficiency. The approach neither requires precalculated conformations of the molecules nor does it make simplifying assumptions on the topology of the molecules being compared. Graph-based molecular alignment produces alignments that are consistent with the chemistry of the molecules as well as their general structure, as it depends on both the local connectivities between atoms and the overall topology of the molecules. Results from extensive evaluation suggest that, for most practical purposes, graph-based molecular alignment is a viable alternative to molecular field alignment with respect to structural superposition and leads to structures of comparable quality in a fraction of the time, taking on average less than 0.1 sec per molecule pair. GMA can claim to be the fastest available explicitly flexible molecular alignment method.
HomDock ⁴ is a combination of the ligand based GMA molecular alignment tool and the docking tool GlamDock. It is used to improve docking accuracy and efficiency in cases where a complex structure of a ligand with the target protein is known. The approach can be extended to cases where a known ligand exists, however the complex structure is unknown, so only the identity of an active molecule is needed to improve efficiency of docking. HomDock docks in less than 0.5 seconds on average on a standard PC, and shows significantly higher accuracy than normal docking in cross docking benchmarks .
Fuzzee allows the identification of functionally similar molecules, based upon functional and structural groups or fragments. The softening of the similarity definition of molecules allows scaffold hopping without additional effort. The algorithm can be used for the identification of topologically different molecules that share similar physico-chemical features. Compared to competing reduced graph or tree based approaches it has the advantage that it allows a weighted matching on the one hand and does not make assumptions on the topology of the molecules on the hand. Fuzzee is highly efficient, allowing more than 1.000 comparisons per second.

COSMOtherm:- calculation of solvation mixture thermodynamics
COSMOtherm predicts a wide range of properties for mixtures and pure compounds, such as boiling points, vapor pressures, solubilities, ADME properties, viscosities, partition coefficients, phase equilibria, phase diagrams, azeotropes, heat of mixing, reaction thermodynamics, activity coefficients, sigma profiles, pKa and much more.
COSMOtherm: Application Examples
The following examples demonstrate some of COSMOtherm's capacities in chemical and engineering thermodynamics:
- Vapour-Liquid binary phase diagrams
- Activity coefficients
- Excess properties
- Isomeric effects
- Temperature dependency
As a new feature, COSMOtherm now is able to generate VRML files for the visualization of the screening charge density s on the molecular surface. This gives a very vivid picture of the molecules, showing the local positions of strongly interacting sites. Even details like lone-pairs are well resolved. Note, that s is a much more local and detailed property compared to electrostatic potential (ESP).
CRYSTAL:- Computes the electronic structure of periodic systems
CRYSTAL is a general-purpose program for the study of crystalline solids, and the first which has been distributed publicly. The first version was released in 1988 and then five next versions have followed: CRYSTAL92, CRYSTAL95, CRYSTAL98, CRYSTAL03 and CRYSTAL06 and now CRYSTAL09..
The CRYSTAL program computes the electronic structure of periodic systems within Hartree Fock, density functional or various hybrid approximations. The Bloch functions of the periodic systems are expanded as linear combinations of atom centred Gaussian functions. Powerful screening techniques are used to exploit real space locality. Restricted (Closed Shell) and Unrestricted (Spin-polarized) calculations can be performed with all-electron and valence-only basis sets with effective core pseudo-potentials.
The program can automatically handle space symmetry (230 space groups, 80 two-sided plane groups, 99 rod groups, 45 point groups are available ). Point symmetries compatible with translation symmetry are provided for molecules. Helical symmetry is now available (up to order 48). Input tools allow the generation of a slab (2D system), or a cluster (0D system), from a 3D crystalline structure, or the creation of a supercell with a defect, or nanotubes (1D system) from a single-layer slab model (2D system).
The code may be used to perform consistent studies of the physical and chemical properties of molecules, polymers, surfaces and crystalline solids:

Crystal Explorer :- Crystal structure analysis
What can CrystalExplorer do for you?
CrystalExplorer can display a two dimensional representation of the Hirshfeld surface, which is referred to as a "fingerprint" of the crystal. This can help uniquely classify a crystal, even polymorphic crystals.
The Hirshfeld surfaces in CrystalExplorer give a novel alternative view of the crystal, which may enable you to see trends that are not apparent otherwise.
CrystalExplorer enables you to view a CIF containing multiple crystal structures, and measure distances and angles within the crystal. All molecules and surfaces are displayed in three dimensions; with rotation, translation and zooming of the viewpoint.
CrystalExplorer is interfaced to the free software Tonto. As a result, it can calculate SCF energies of and obtain molecular orbitals for any fragments of the crystal. Once molecular orbitals are obtained, they can be used to generate quantum mechanical isosurfaces which are then displayed.
