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

Restriction the limit-values of a parameter
Roberto Fernández de Luis | Wed, Jan 28, 2026
Hi all,
I am working on a powder-diffraction data fitting with MOF materials. I have defined a Rigid-block of the two crystallographically independent molecules, and I have tried to refine the occupancy factor of each of them. For one, this values surpass slightly the maximum expected value of 1.0. I would like to kwno if there is a posibility to resctrict the maximum and minimum values for a specific variable in Jana2006.
Many thanks
Roberto

Neumann, Erik | Wed, Jan 28, 2026
(updated Wed, Jan 28, 2026)
Hello Jana-Developer Team, i run the Version 2.1 and i have problems with Jana crashing, when i want to open Vesta. When i check for Updates it says, that there is already Version 2.2. On the Website though i cannot see this version.
Michal Dušek Wed, Jan 28, 2026
Hello,
This was a bug in the web page, which has been removed today. The version is 2.2.
Best wishes,

Where is manual for Jana2020????
Michal Dušek | Thu, Jun 5, 2025
(updated Wed, Jan 28, 2026)
There is no manual for the Jana2020 program that summarizes all its features. Most of the theoretical foundations are detailed in the manual for Jana98 and a few other documents outlined in the "About Jana" section. The primary resource for using the program is the Jana2020 Cookbook, which includes resolved examples for various model situations.

Where can I find the manual for jana98? Can someone provide me with a download link? Thank you so much.
