...It can read experimental data from several data formats (spec, edf, xrdml, ...); convert them to reciprocal space for arbitrary goniometer geometries and different detector systems (point, linear as well as area detectors); for further processing the data can be gridded (transformed to a regular grid). More detailed description as well as documentation can be found at webpage http://xrayutilities.sourceforge.io/. Downloads for windows can be found on http://pypi.python.org/pypi/xrayutilities Development is performed on github: https://github.com/dkriegner/xrayutilities

Sombrero is a fast wavelet image processing and object detection C library for astronomical images. Sombrero is named after the "Mexican Hat" shape of the wavelet masks used in image convolution and is released under the GNU LGPL library.

...While our focus is on high-order finite elements, the approach is mostly algebraic and thus applicable to other discretizations in factored form, as explained in the user manual and API implementation portion of the documentation. One of the challenges with high-order methods is that a global sparse matrix is no longer a good representation of a high-order linear operator, both with respect to the FLOPs needed for its evaluation, as well as the memory transfer needed for a matvec. Thus, high-order methods require a new "format" that still represents a linear (or more generally non-linear) operator, but not through a sparse matrix.

GtkDatabox is a widget for live display of large amounts of fluctuating numerical data. Data presentation (e.g. on linear or logarithmic scales, as dots or lines, with markers/labels) as well as user interaction (e.g. measuring distances) is easy.

RNAfdl is a highly flexible tool for drawing RNA secondary structures. Secondary structures can be visualized as classical secondary structure plot, circle plot, linear plot or mountain plot. RNAfdl allows manual editing and several drawing styles, as well as a fully automated conjugate gradients minimization approach to draw more complex structures without user interaction. In addition, RNAfdl allows you to incorporate non-canonical base pairs into drawings.

ViNSS View is a highly flexible tool for drawing RNA secondary structures. Secondary structures can be visualized as classical secondary structure plot, circle plot, linear plot or mountain plot. ViNSS View allows manual editing and several drawing styles, as well as a fully automated conjugate gradients minimization approach to draw more complex structures without user interaction. In addition, ViNSS View allows you to incorporate non-canonical base pairs into your drawing.

given three point that are not co-linear in the object or image space return a rotation matrix and offset that allows image points to be projected back into object space.

PyramidWorkshop is an image-compression System based upon the scientific work of John Robinson (inventor of BTPC) about image-compression with adaptive linear predictors and is in average more efficient than PNG/JPEG2000.

A set of library functions to generate pPostScript plots to file or printer. Several levels of user interface, highest level includes virtual windows, autoscale etc. Supported graphs are linear, logarithmic and polar plots. Lower levels include standard
