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.

The CMWS Model, currently written in Python, compiles model runs of the Operational GFS and NAM computer model outputs by NOAA for providing a numerical weather forecast using statistical forecasting.

IMOD is a set of image processing, modeling and display programs used for tomographic reconstruction and for 3D reconstruction of EM serial sections and optical sections.
The package contains tools for assembling and aligning data within multiple types and sizes of image stacks, viewing 3-D data from any orientation, and modeling and display of the image files. IMOD was developed primarily by David Mastronarde, Rick Gaudette, Sue Held, and Jim Kremer at the Boulder Laboratory for 3-D Electron Microscopy of Cells.
Enhancements:
- The model structure has been enhanced to contain fine-grained display properties, so that several display features (color, transparency, line width, symbol display) can be changed for individual points within a contour or contours or surfaces within an object. Multiple openings (gaps) in a contour can also be created. The features can be set and visualized in 3dmod, and imodmesh encodes the features into a mesh.
- eTomo can now process montaged data and has an improved window layout for working on dual-axis data sets.
- eTomo provides an interface for running two of the steps on multiple computers or processors, and a mechanism for specifying the available machines.
- The bead tracker has been improved and can track in local areas, which greatly improves its performance for data sets covering large areas.

Distillation Designaer v1.0.1 is designed as a useful and easy-to-use binary distillation modeling tool using the McCabe-Thiele method. It will be of use to students studying Chemical Engineering and is currently being offered as 'donation ware'.

Major Features:

1. Boiling Point Graph showing Vapour-Liquid Compositions.
2. q-Line calculation from component thermodynamic properties.
3. Manually defining the minimum reflux ratio.
4. Loading of Data files.
5. Plot of Reflux versus stages to help determine the optimal value.
6. Drag and Drop graphs direct to desktop.
7. Configurable printing of the 3 Graphs
8. Much better checking of input data before the McCabe-Thiele graph can be plotted.
9. Very basic help.

In the United States, 5 million individuals have heart failure. Each year, 550 000 new cases are diagnosed, and there are 1 million hospitalizations. The direct and indirect costs of heart failure are estimated at $29 billion per year.

Although heart failure presents enormous healthcare burdens, outcomes in heart failure are highly variable, with annual mortality varying from 5% to 75%. Physicians need to counsel patients about prognosis to enable informed decisions about medications, devices, transplantation, and end-of-life care.

Previous heart failure (HF) risk models stratify patients into three risk groups using peak oxygen consumption (VO2). An individualized estimate of survival in HF has not been reported. The Seattle Heart Failure Model was derived by retrospectively investigating predictors of survival among 1,125 HF patients in PRAISE1 (NYHA 3B-4, EF<<less
