This webpage provides links to my personal webpage and some of the software developed by me. The programs are free for all academic users and registration is not necessary, however I expect you to write me some feedback. Once I have got your e-mail, I will be able to notify you about updates.


OLEX is new software for visualisation and analysis of the extended structures. The software has a mouse driven Windows® compliant interface, which facilitates the analysis and visualisation process. A set of standard crystallographic operations is also incorporated into OLEX. Thus the user can measure bond lengths, interatomic distances, angles between bonds and planes; create centroids and more. One of the main features of the software is the construction of topological networks and evaluation of topological (vertex) symbols for a given node. The topological analysis is usually performed to analyse the connectivity of a given extended structure and allows its classification and comparison with the others. The possibility to analyse interpenetrating networks and networks partially or fully constructed of hydrogen bonds and previously mentioned features make OLEX indispensable tool for quick structure analysis.
The graphical kernel of OLEX is build on the Silicon Graphics OpenGL® library, which makes the pictures produced by it look similar to other software packages. Some extra features of the graphical system is the possibility to draw on semitransparent pictures and create your own gradients. Examples of pictures and gradients produced using OLEX are shown on this page. For more examples of gradients see the OLEX Art page.
To find out more about OLEX read our paper
 Dolomanov O. V, Blake A. J., Champness N. R. and Schröder, M. (2003).  J. Appl. Cryst., 36, 1283-1284.
and the introduction on the OLEX webpage.


LCELLS is an efficient search engine for laboratory unit cells. In general the software allows automatic unit cell parameters collection from existing INS or CIF files and later to perform the cell search on the established database.
The software is described in the following paper:
Dolomanov O. V, Blake A. J., Champness N. R. and Schröder, M. (2003).  J. Appl. Cryst., 36, 955.

XFolders is a convenient projects organiser which incorporates several crystallographic tools including customisable HTML/Word tables producing and CIF data merging and extracting. The program also performs a role of shell application - an adjustable toolbar allows adding new buttons linked to external software.


A small convenient program for calculation of CHN. The main feature of the program is the possibility of automatic calculation of the amount of given solvent to fit given CHN values. Additionally, the program calculates the ISOTOPIC pattern for the given formula.


Some handy utilities which I have developed for my/your convenience.
