checkboxes are not active for clicking they are simply shaded in grey and cannot be added or removed which means that these parameters are always taken into account when refining my system is windows

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 faq attachment optional send cancel naveen kumar chogondahalli muniraju wed oct 1 2025 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 naveen mariam pogosova wed oct 8 2025 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 listed space group is incompatible with laue class klar paul benjamin mon oct 5 2026 there seems to be a problem with the symmetry wizard a colleague encountered a case where the space group selection menu offered one orthorhomic space group pccm alongside several monoclinic space groups although in the menu before laue class 2 m was selected the unit cell angle beta is about 100 degrees and there is no orthorhombic candidate supercell the symmetry selection then moves on with problems all unit cell angles in the m50 file are set to 90 degrees and the selection of the correct space group p 1 21 1 fails with an error message like the one shown in the screenshot i only have the attached screenshot i could get the jana files from my colleague if needed independent of this bug report the footer of this very page has a little typo jana is develo pp ed at attachments symmetry_bug_screenshot 2026 10 05 161915 png bug attachment optional send cancel problem with occupancies hafsa zeroual sat sep 26 2026 updated thu oct 1 2026 hello i am refining occupancies of atoms with shared positions and adps and an overall occupancy sum constrained to 1 i don t understand why jana2020 does not respect this constraint at all e g sometimes it gives occupancies of 2 for one atom or a negative occupancy or a sum that exceeds 1 i checked the refinement restrictions and it was well written there thank you in advance for your reply other attachment optional send cancel michal dušek thu oct 1 2026 hello if one occupancy is negative and the other positive and their sum equals 1 this means the mixed elements are either in contradiction with the diffraction data or the diffraction data are not accurate enough to distinguish these elements the second case could be detected by fixing the elements in various ratios and seeing the effect on the r values on the other hand if the sum is not 1 it might be a problem with the initial occupancy values since we usually keep their overall sum if you don t use equations best wishes michal refined data export jhuma sannigrahi tue may 19 2026 updated tue aug 25
