Jana2006 is a crystallographic program focused to solution, refinement and interpretation of difficult, especially modulated structures. It calculates structures having up to three modulation vectors from powder as well as single crystal data measured with X-ray or neutron diffraction. The input diffraction data can be unlimitedly combined, the combination of powder neutron data with single crystal X-ray data being a typical example. The structure solution can be done using the built-in charge flipping algorithm or by calling an external direct methods program. Jana can handle multiphase structures (for both powder and single crystal data), merohedric twins as well as twins with partial overlap of diffraction spots, commensurate and composite structures. It contains powerful transformation tools for symmetry (group-subgroup relations), cell parameters and commensurate-supercell relations. Wide scale of constrains and restrains is available including a powerful rigid body approach and possibility to define a local symmetry affecting only part of the structure. The latest development of Jana concerns magnetic structures.

July 25, 2008  The first stable version of Jana2006 for Windows. This program is the successor of Jana2000. Currently only Windows version is available, Unix version as well as manual are under development. The Stable version will be changed occassionally, the everyday work will be immediately available in the Latest version. Registered users will be informed about new Stable versions. Jana2006 can be obtained in Download area.
July 22, 2008  New web page for Jana contains all information about Jana2006 and the previous version Jana2000. We have partially changed also download locations, please do not use old links.
December 28, 2007  Final version of Jana2000 - see the Download area. No further development is expected in Jana2000.
Jana system is a freeware but we are interested who is using it. We would like our users to register. Registered users get e-mails about major updates.
Jana2000: development of this program has been finished. Jana2000 input files can be used in Jana2006, the necessary conversions are done automatically.
Jana2006 for UNIX: porting of Jana2006 to UNIX is in progress but it is not yet finished.
User manuals: not yet available. The old manuals for Jana98 and Jana2000 are still partially useful.

STABLE versions are not frequently changed, registered users get information about their releases. LATEST versions are changed frequently and contain the latest development. FINAL versions are not further developed. BETA versions are pre-releases of new major upgrades.
Jana2006 for Windows. Execute janainst.msi and follow the instructions. Execute jana2006.exe and check the version string in Tools->About Jana2006.
Jana2006 for Windows, old way of installation from janainst.exe. Follow the instructions for Jana2000. For the system environment variable use the name JANA2006DIR instead of JANADIR.
Jana2006 for UNIX. Unix version is not yet available.
Jana2000 for Windows. Execute the self-extracting archive janainst.exe. Before the extraction choose installation directory. After the extraction go to Control panel - System - Advanced - Environment variables and set the system-wide environment variable JANADIR to the name of the installation directory. Go to Display Properties - Effects and make sure Clear type fonts are not used for smoothing edges of screen fonts. Execute jana2000.exe.
For upgrade execute the self-extracting archive janainst.exe and choose the same installation directory where the original version of Jana2000 has been installed.
Jana2000 for UNIX, fresh installation. Requisities: FORTRAN compiler, C compiler, SDK for X11. Download jana2000Pack.exe and put it one level above the future installation directory (for jana2000Pack.exe in directory xxx, the installation directory will be xxx/jana2000). Start csh or tcsh, execute `source jana2000Pack.exe' and follow instructions of the installation procedure. No JANADIR is necessary if the installation stays in the default directory.
Common troubleshooting for Windows.
  • Premature end of instalation from janainst.msi: often caused by Adobe Acrobat updater, which must be killed from task manager
  • Installation from janainst.exe: Make sure that JANADIR or JANA2006DIR contains correct name of installation directory.
  • Installation from CD: Make sure that files copied from CD are not read-only.
  • Jana2000 cannot be used with Clear type fonts.
  • Installation directory should not be Desktop (too complicated pathname) or flashdisk (too slow)
  • Installation from janainst.msi over older version installed from janainst.exe: in most cases it runs normally. The installation procedure sets automatically system environment variable JANA2006DIR but does not define the user environment variable. In case of version mismatch please ensure that the user variable JANA2006DIR is undefined.
    In rare cases the installation from janainst.msi leaves the original files unchanged. This can be recognized in Tools->About where the version string is not updated after installation. In such case the installation directory of Jana2006 should be deleted (keep copy of ini and hst file) as well as the user or system environment variable JANA2006. Then repeat installation from janainst.msi.
Common troubleshooting for UNIX. Make sure SDK for X11 is installed, in most Linux distributions only run-time libraries are present by default. The installed Jana executable cannot be moved from the default installation directory jana2000 without special arrangements.

Ad hoc workshops on Jana
Ad hoc workshops are small two days workshops organized in Praha by authors of Jana software. A new workshop is usually organized when we find an overlap in topics in the list of preliminary registrations for at least five people. In such case the program details and the dates are discussed with participants and fixed. Another participants can register for a workshop with fixed program and date up to 12-15 people. Participants pay themselves all their expenses and they are expected to bring their own laptops with Windows. However, we can lend one or two laptops to those who cannot bring their own ones. The registration fee is zero (in Czech Crowns). Workshop certificates are issued by our skilled artists on demand.

Registration By e-mail to Michal Dusek ( For workshops without fixed program or for future not yet announced workshops please give a list of selected topics, rated by importance. Although a workshop can usually have only four topics (one topic takes 1/2 of day) the number of selected topics can be higher, it helps finding overlaps. Please indicate if you have already experience with Jana software. New users should select the topic "INT1". Those who would like to participate in an advanced workshop (without INT1) but don't have an experience with Jana should make Example 1.1 and 2.1 of the cookbook as a homework.
