BINoculars is a tool for data reduction and analysis of large sets of surface diffraction data that have been acquired with a two-dimensional X-ray detector. The intensity of each pixel of a two-dimensional detector is projected onto a three-dimensional grid in reciprocal-lattice coordinates using a binning algorithm. This allows for fast acquisition and processing of high-resolution data sets and results in a significant reduction of the size of the data set. The subsequent analysis then proceeds in reciprocal space. It has evolved from the specific needs of the ID03 beamline at the ESRF, but it has a modular design and can be easily adjusted and extended to work with data from other beamlines or from other measurement techniques.

Finalcif is a full-featured CIF file editor to make editing and validation of CIF files easy. It collects all the information from a work folder needed in order to finalize a CIF file for publication. In any case, one can also import a valid CIF file to complete the information. In ideal cases, it takes one click to have a publication-ready file.

Essentially, one should have the corresponding CIF file for FinalCif in its original 'work' folder, which contains all other files such as SAINT list files, SADABS list file, SHELX list files, etc. that led to this CIF file.

Checking the final CIF file with the IUCr CheckCIF server is a one-click problem in FinalCif. One gets a web and PDF report or just a local PLATON CIF check for computers without internet.

FinalCif generates beautiful CIF reports in seconds for publication as MS Word files (also compatible with Openoffice etc.). The report includes tables of structure properties like R-values or atom parameters and a report text about the experiment conditions.

The button "save cif file" saves the current file under 'name'-finalcif.cif. FinalCif will never make changes to the original CIF file.

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.

The lmfit Python package provides a simple, flexible interface to non-linear optimization or curve fitting problems. The package extends the optimization capabilities of scipy.optimize by replacing floating pointing values for the variables to be optimized with Parameter objects. These Parameters can be fixed or varied, have upper and/or lower bounds placed on its value, or written as an algebraic expression of other Parameters.

The principal advantage of using Parameters instead of simple variables is that the objective function does not have to be rewritten to reflect every change of what is varied in the fit, or what relationships or constraints are placed on the Parameters. This means a scientific programmer can write a general model that encapsulates the phenomenon to be optimized, and then allow user of that model to change what is varied and fixed, what range of values is acceptable for Parameters, and what constraints are placed on the model. The ease with which the model can be changed also allows one to easily test the significance of certain Parameters in a fitting model.

The lmfit package allows a choice of several optimization methods available from scipy.optimize. The default, and by far best tested optimization method used is the Levenberg-Marquardt algorithm from MINPACK-1 as implemented in scipy.optimize.leastsq. This method is by far the most tested and best support method in lmfit, and much of this document assumes this algorithm is used unless explicitly stated. An important point for many scientific analysis is that this is only method that automatically estimates uncertainties and correlations between fitted variables from the covariance matrix calculated during the fit.

A few other optimization routines are also supported, including Nelder-Mead simplex downhill, Powell's method, COBYLA, Sequential Least Squares methods as implemented in scipy.optimize.fmin, and several others from scipy.optimize. In their native form, some of these methods setting allow upper or lower bounds on parameter variables, or adding constraints on fitted variables. By using Parameter objects, lmfit allows bounds and constraints for all of these methods, and makes it easy to swap between methods without hanging the objective function or set of Parameters.

Finally, because the approach derived from MINPACK-1 usin the covariance matrix to determine uncertainties is sometimes questioned (and sometimes rightly so), lmfit supports methods to do a brute force search of the confidence intervals and correlations for sets of parameters.

This is the Python 3 version of the package.

V_Sim visualizes atomic structures such as crystals, grain boundaries, molecules and so on (either in binary format, or in plain text format).

The rendering is done in pseudo-3D with spheres (atoms) or arrows (spins). The user can interact through many functions to choose the view, set the bindings, draw cutting planes, compute surfaces from scalar fields, duplicate nodes, measure geometry... Moreover V_Sim allows one to export the view as images in PNG, JPG, PDF (bitmap), SVG (scheme) and other formats. Some tools are also available to colorize atoms from data values or to animate on screen many position files.

The analysis of macromolecular structures often requires a comprehensive definition of atomic neighborhoods. Such a definition can be based on the Voronoi diagram of balls, where each ball represents an atom of some van der Waals radius. Voronota is a software tool for finding all the vertices of the Voronoi diagram of balls. Such vertices correspond to the centers of the empty tangent spheres defined by quadruples of balls. Voronota is especially suitable for processing three-dimensional structures of biological macromolecules such as proteins and RNA.

Since version 1.2 Voronota also uses the Voronoi vertices to construct inter-atom contact surfaces and solvent accessible surfaces. Voronota provides tools to query contacts, generate contacts graphics, compare contacts and evaluate quality of protein structural models using contacts.
