PAN Blend data-reduction-frameworks packages

Fityk is a flexible and portable program for nonlinear fitting of analytical functions (especially peak-shaped) to data (usually experimental data). In other words, for nonlinear peak separation and analysis.

It was developed for analyzing diffraction patterns, but can be also used in other fields, since concepts and operations specific for crystallography are separated from the rest of the program.

Fityk offers various nonlinear fitting methods, subtracting background, calibrating data, easy placement of peaks and changing peak parameters, automation of common tasks with scripts, and much more. The main advantage of the program is flexibility - parameters of peaks can be arbitrarily bound to each other, eg. the width of a peak can be an independent variable, can be the same as the width of another peak or can be given by a complicated - common to all peaks - formula.

libjs-sphinxdoc is necessary for the Javascript stuff in the documentation.

Gnuplot is a portable command-line driven interactive data and function plotting utility that supports lots of output formats, including drivers for many printers, (La)TeX, (x)fig, Postscript, and so on. The X11-output is packaged in gnuplot-x11.

Data files and self-defined functions can be manipulated by the internal C-like language. Can perform smoothing, spline-fitting, or nonlinear fits, and can work with complex numbers.

This metapackage is to install a full-featured gnuplot (-qt, -x11 or -nox).

It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw". It supports "stacks", a series of images that share a single window.

It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles. It can create density histograms and line profile plots. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering.

Spatial calibration is available to provide real world dimensional measurements in units such as millimeters. Density or gray scale calibration is also available.

ImageJ is developed by Wayne Rasband (wayne@codon.nih.gov), is at the Research Services Branch, National Institute of Mental Health, Bethesda, Maryland, USA.

xylib is a C++ library for reading files that contain x-y data from powder diffraction, spectroscopy and other experimental methods.

This package contains a small program xyconv that converts files supported by the xylib library to TSV (tab-separated values).

Ngraph is the program to create scientific 2-dimensional graphs for researchers and engineers. This program can create advanced graphs which can't be created by spreadsheets. Graphs can be exported to postscript.

Octave is a (mostly MATLAB® compatible) high-level language, primarily intended for numerical computations. It provides a convenient command-line interface for solving linear and nonlinear problems numerically.

Octave can be dynamically extended with user-supplied C++ files.

PyMca is set of applications and Python libraries for analysis of X-ray fluorescence spectra.

The applications included in this package are:

• edfviewer - Display and inspection of data files in ESRF Data Format
• elementsinfo - Displays element specific X-ray data
• mca2edf - Converts files from SPEC MCA format to EDF
• peakidentifier - Displays X-ray fluorescence peaks in a given energy range
• pymcabatch - Batch fitting of spectra
• pymcapostbatch - Post-processing of batch fitting results
• pymca - Interactive data-analysis
• pymcaroitool - Region-of-interest (ROI) imaging tool

The PyMca toolkit can read data files in SPEC, ESRF data file (EDF), OMNIC, HDF5, AIFIRA and SupaVisio formats.

This are the scripts of the package.

Scilab is a matrix-based scientific software package. Scilab contains hundreds of built-in mathematical functions, rich data structures (including polynomials, rationals, linear systems, lists, etc...) and comes with a number of specific toolboxes for control, signal processing, ...

This package also provides Xcos, a graphical editor to design hybrid dynamical systems models. Models can be designed, loaded, saved, compiled and simulated. Stable and efficient solution for industrial and academics needs, Xcos provides functionalities for modeling of mechanical systems (automotive, aeronautics...), hydraulic circuits (dam, pipe modeling...), control systems, etc. Modelica capabilities are also provided.

For a minimum version of scilab, install package "scilab-cli".

The silx project aims at providing a collection of Python packages to support the development of data assessment, reduction and analysis applications at synchrotron radiation facilities. It aims at providing reading/writing different file formats, data reduction routines and a set of Qt widgets to browse and visualize data.

The current version provides :

• reading HDF5 file format (with support of SPEC file format)
• histogramming
• fitting
• 1D and 2D visualization using multiple backends (matplotlib or OpenGL)
• image plot widget with a set of associated tools (See changelog file).
• Unified browser for HDF5, SPEC and image file formats supporting inspection and visualization of n-dimensional datasets.
• Unified viewer (silx view filename) for HDF5, SPEC and image file formats
• OpenGL-based widget to display 3D scalar field with isosurface and cutting plane.

This uses the Python 3 version of the package.

Spyder (previously known as Pydee) is a free open-source Python development environment providing MATLAB-like features in a simple and light-weighted software

This is a transitional package depending on the spyder package (which provides the application for Python 3). It can be removed after installation.

VisTrails is an open-source scientific workflow and provenance management system developed at the University of Utah that provides support for data exploration and visualization. Whereas workflows have been traditionally used to automate repetitive tasks, for applications that are exploratory in nature, such as simulations, data analysis and visualization, very little is repeated---change is the norm. As an engineer or scientist generates and evaluates hypotheses about data under study, a series of different, albeit related, workflows are created while a workflow is adjusted in an interactive process. VisTrails was designed to manage these rapidly-evolving workflows.

Maxima is a fully symbolic computation program. It is full featured doing symbolic manipulation of polynomials, matrices, rational functions, integration, Todd-coxeter methods for finite group analysis, graphing, multiple precision floating point computation. It has a symbolic source level debugger for maxima code. Maxima is based on the original Macsyma developed at MIT in the 1970s. It is quite reliable, and has good garbage collection, and no memory leaks. It comes with hundreds of self tests.

This package contains an X Windows interface using the tcl/tk libraries.

provides metadata and data access for scientific datasets, using OPeNDAP, OGC WMS and WCS, HTTP, and other remote data access protocols.

This R package provides functions that simulate the operation of a CCD area detector of the type commonly used in macromolecular X-ray crystallography. In addition to the simulation, functions allowing display, integration and statistical analysis of diffraction spot images are also included.

DISP was written to investigate possible improvements to error estimation for diffraction spot integration of data recorded on CCD detectors. That work was published in Waterman & Evans. Estimation of errors in diffraction data measured by CCD area detectors. Journal of Applied Crystallography 43(6), 2010.

NeXpy is designed to provide an intuitive interactive toolbox allowing users both to access existing NeXus files and to create new NeXus-conforming data structures without expert knowledge of the file format.
