Free modelers software for mac

MODELLER is used for homology or comparative modeling of protein three-dimensional structures. The user provides an alignment of a sequence to be modeled with known related structures and MODELLER automatically calculates a model containing all non-hydrogen atoms.
MODELLER implements comparative protein structure modeling by satisfaction of spatial restraints, and can perform many additional tasks, including de novo modeling of loops in protein structures, optimization of various models of protein structure with respect to a flexibly defined objective function, multiple alignment of protein sequences and/or structures, clustering, searching of sequence databases, comparison of protein structures, etc.
Note: In order to use the program you need to register first.
Enhancements:
- Removal of limits on the number of pseudo atoms, segments, the length of file names and most other strings, and the number of parameters in parameter files.
- Removal of the read_restyp() command. To read a user-defined residue type file, set restyp_lib_file when creating an environ object.
- Bug fix: the correct VDW radii (as selected by topology.submodel) are now used for PSA calculations (previously the all-hydrogen radii were used in all cases).
- Improved error handling: almost all errors should be recoverable now (using the standard Python exception handling mechanism) and incorrect input should trigger an error rather than causing Modeller to crash (please report any crashes as bugs to the developers).
- SALIGN bug fixes, improved binning of access classes.
- Modeller scripts are now more like real Python scripts; the PYTHONPATH environment variable is honored, and additional command line arguments can be given to your scripts (accessible as sys.argv).
- Bug fix for alignment.segment_matching(): correct alignment scores are now written.
- Support for AMD64 and EM64T (Opteron/Xeon64) Linux machines.
- DOPE model assessment now returns only the DOPE energy itself by default, ignoring other energy terms.
- Bug fix for model.restraints.pick() when used with absolute position restraints; always allow 1-atom restraints to pass the residue_span_range check.

Requirements:
Mac OS X 10.2 or later. For best performance, a Quartz Extreme compatible AGP video card is required.

Enhancements:
Version 0.9.5: Updated to shell version 1.6. See "About the Shell" for changes.

GEMS is designed to allow developers to rapidly create a graphical modeling tool with no coding and immediately begin addressing the challenging aspects of these types of complex domains.
GEMS provides extensive support for integrating intelligent mechanisms into a modeling tool to provide visual modeling queues, simulation, constraint-compliant batch processing, and analysis.
The goal of the Generic Eclipse Modeling System (GEMS) is to bridge the gap between the communities experienced with visual metamodeling tools, such as the Generic Modeling Environment (GME), and those built around the Eclipse modeling technologies, such as the Eclipse Modeling Framework (EMF) and Graphical Modeling Framework (GMF).
GEMS is an open project and encourages developers to extend, enhance, and use its tools. GEMS has been developed in conjunction with research work done in collaboration with Siemens, IBM, and PrismTech. GEMS is an open source project, based on the Eclipse License.
Main features:
- A graphical language for metamodel specification that can capture
- domain entities
- attributes of entities
- inheritance relationships
- connection and containment relationships between entities
- distinct modeling views
- graphical information, such as connection styles, colors, and fonts
- constraints
- GEMS provides extensive support for intelligent modeling guidance including
- automatic solving of inference-based constraints for connection and containment
- applying batch changes to a model that are guided by a set of global constraints
- visually suggesting connection endpoints and element parents that conform to the specified constraints
- support for simulations
- mechanisms for integrating constraint solvers
- mechanisms for creating re-usable templatized constraint solvers
- mechanisms for discovering why a model cannot meet a set of global domain constraints
- graphical mechanisms for suggesting optimal modeling decisions derived from a constraint solver
- A code generation framework, which does not require any coding or XML editing, for transforming a GEMS metamodel into a working Draw2D/GEF Eclipse plug-in for editing instances of the language
- Ecore Model
- EMF Classes
- GEF/Draw2D Figures
- GEF/Draw2D Edit Parts
- other GEF/Draw2D Infrastructure for creating the palette, etc.
- plugin descriptor for the tool
- build descriptor for the project
- classpath descriptor for the project
- The visual appearance of the generated modeling tool can be customized by creating CSS stylesheets to modify the icons, colors, fonts, connection styles, and other visual attributes of the modeling entities
- The views available to a modeler can be customized through a mechanism similar to CSS stylesheets
- The generated graphical modeling plug-ins, created by GEMS, support extensive external customization through extension points for
- adding code generators and transformation, such as Open Architecture Ware, Java Emitter Templates, and Atlas Transformation Language
- model pre and post processing
- model event listeners
- triggers for invoking actions (similar to database triggers)
- constraint languages
- menus
- palette customizers
- intelligent modeling guides
- model serializers
- GEMS provides built-in support for constraints written in Java, OCL, and Prolog
- constraints can also be used as triggers for invoking actions
- Models and constraint solvers can be accessed remotely using a built-in CORBA server
System requirements:
- Java 1.5 (or higher), the Eclipse Modeling Framework, and the Graphical Editor Framework.

Ldglite is a program that lets you view and edit Lego brick models stored in LDRAW format. It was created by connecting the LDLite DAT file parser to an OpenGL rendering engine, making it portable to other operating systems.

Along the way the L3 parser from L3P and a few nifty features from other DAT file viewers such as L3Lab were added or emulated. Most recently, an LEdit emulation mode was added. This gives you the ability to create and edit models in ldglite in addition to the viewing capabilities.

Another new feature is the ability to function as a cheesy scene modeler for l3p and POV. Several internet sites use ldglite as a scripted offscreen renderer, generating many pictures of ldraw parts for inventory lists and such. Possibly the most important feature of ldglite is that all of the source code is available.

Requirements:
MacOS X 10.0 or later.
