Upgrades and patches
Michal Dušek | Tue, Jul 29, 2025
(updated Wed, Oct 8, 2025)
Upgrades for Jana2020 are available several times a year. In between these upgrades, ongoing development of the program occurs, resulting in patches that are released very frequently, sometimes even several times a week.
To obtain the correct patch, you must first install the latest version of the program from the Downloads section on the program's website. After launching the program, you can download the patch by clicking the "Download patch" button in the About section of Jana2020. This will download the file jana2020-patch.exe, which can be found in the directory where the program is installed.
Next, you’ll need to complete a few manual steps: first, close the program and rename jana2020-patch.exe to jana2020.exe. Then, reopen the program and check in the About section of Jana2020 using the "Detailed info" button to confirm that you are indeed using the correct patch.

Dear Michal,
I am running the latest version available for download, #1.3.61. It is not possible to patch it since it does not correspond to the 'newest version 2.1'. Where can I obtain the installation files of version 2.1?
Thank you.

Dear Jana-developers team,
Recently, I found a publication devoted to the better evaluation of the Theta shift for the case of Debye-Scherrer geometry combined with the flat 2D detector.
(Please see the article doi.org/10.1107/S1600576722011360)
I would love to hear your thoughts on this. Seemingly, such a setup is fairly common (I see it often in synchrotron setups) - and, maybe, you might consider adding a similar equation / function in further Jana updates?
Do you think the existing Theta shift tools (zero shift / sycos / sysin) can still effectively describe the shifts observed in such a setup (Debye-Scherrer + 2D detector)?
Perhaps you could recommend which option among the existing ones would be the best choice?
I would deeply appreciate your response.
Thank you very much for your time!
Sincerely,
Mariam

Can Jana2020 refine the occupancy ratio of co-occupied atoms with a quantity exceeding three?
YangWenlin | Sat, Oct 11, 2025
(updated Sat, Oct 11, 2025)
Hello jana team:
When an atom is replaced by multiple atoms, such as rare earth elements replacing Ca, we set the refinement restrict 'Ca1 1 La Ce1', and jana2020 always ignores the middle atom. How to set the refinement restrict parameter so that it can freely refine the occupancy ratio of these three elements?
Sincerely looking forward to your reply.
thank you

Download link is broken?

Hello Jana team,
When I attempt to download the 2020 version I am met with a 404 not found error.
Kind regards,
Hunter

Instead of left-clicking on the download link, right-click on the link and 'save link as' to save the 'Jana2020Inst.msi'.
Best

Hello Hunter,
I was not able to replicate the issue you reported. When I click, I receive a security warning, and then I can download the file without any problems. We were fixing some issues yesterday, so it is possible you encountered a glitch during that time. Please let me know if the problem persists.
Best wishes,
Michal

Can Jana2020 be installed in Program Files?
Michal Dušek | Tue, Aug 5, 2025
(updated Sun, Sep 7, 2025)
Yes! Starting with version 2.1, Jana2020 can be installed in the Program Files. Older versions created temporary files directly in the installation directory, meaning that Jana2020 installed in Program Files needed to be run by an Administrator. However, with version 2.1, temporary files are stored in the %APPDATA% directory, allowing Jana2020 installed in Program Files to be run by a normal user.

Jana2020 window is off the screen

(updated Wed, Aug 27, 2025)
Sometimes, Jana2020 remembers the window's position, which may not be available on your screen. Typically, it retains the position of a very large or secondary monitor that has been disconnected. You can solve this issue by editing the ini file:
- Close the running Jana2020 using its icon in the taskbar or via Task Manager.
- The jana2020.ini file is located in the %APPDATA% directory (starting from version 2.1) or in the installation directory of Jana2020 for older versions.
- Open jana2020.ini in your text editor.
- For Jana2020.WindowX, type 100.
- For Jana2020.WindowY, type 100.
- Start Jana2020.
The coordinates (100, 100) represent the top left corner of the Jana2020 window in pixels, measured from the top left corner of your screen.
