McStas and McXtrace are ongoing projects to create a general tool for simulating neutron (McStas) and X-ray (McXtrace) scattering instruments. The two code variants are distributed independently, but share as much infrastructure and tools as possible. Together they are known under the name of
... [More] McCode.
Both McStas and McXtrace are based on a code-generation mechanism where a high-level specification language defines the instrument to be simulated and the mcstas/mcxtrace code generator produces C code that performs the Monte Carlo Simulation.
McStas and McXtrace both come with comprehensive manuals and a libraries of well-tested components that include most standard elements of neutron- and X-ray- scattering instruments respectively. [Less]
The iFit library (pronounce [eye-fit]) is a set of methods to load, analyze, plot, fit and optimize models, and export results. iFit is based on Matlab, but can also be launched without Matlab license (stand-alone version). It does not currently include advanced graphical user interfaces (GUI), but
... [More] rather focuses on doing the math right. Any text file can be imported straight away, and a set of binary files are supported. Any data dimensionality can be handled, including event based data sets (even though not all methods do work for these). Any model can be assembled for fitting data sets. [Less]
Data Analysis Remote Treatment Service (DARTS) is a remote desktop service based on QEMU that launches virtual machines in the cloud, and displays them in your browser. These machines can be used for e.g. scientific data treatment.
MappedTensor is a Matlab class that looks like a simple Matlab array, with all the data stored on disk. It comes with many methods that allow to treat data in the same way as with in-memory arrays even when these are larger than the available memory. This is known as disk-mapping aka lazy loading.
SKYCHART a Matlab class to plot a sky chart with stars/objects
This class computes and plots the sky seen at given location and time. About 43000 stars and 13000 deep sky objects are considered, as well as the Sun, the Moon and 7 planets. The actual number of rendered objects depends on the zoom level in the sky chart.
