Dear @marc-2 , Thank you very much for reporting the issue and such a detailed description! And sorry about this issue. Yes, there are some reported issues for SAMSON on Ubuntu 26.04 and Wayland. We will try to fix this for the next major SAMSON release, since it involves OpenGL rendering failures in the core of SAMSON.

@DmitriyMarin Thanks!

Hi @Dheeraj-0 , Unfortunately, we discontinue support for older versions of SAMSON, so we cannot recommend or provide an older compatible version. If possible, we suggest trying the latest version of SAMSON on a newer machine that supports macOS 13 or later. Sorry for the inconvenience, and thank you for your understanding.

Hi @Federico-Maria , We have modified the behavior of the importers - they should not create covalent bonds for metal coordinations. It previously considered all connections described in the file as covalent ones. The corresponding modules will be updated automatically for you once you restart SAMSON.

Great! Thanks for checking it!

Hi @Federico-Maria , Sorry about the issue. Currently, SAMSON supports virtual reality only for the Windows Mixed Reality headsets. The virtual reality feature for Meta headsets is not yet available.

@Federico-Maria , Great! Thanks for checking! Thanks for mentioning, the thing in 'About SAMSON' will be fixed with the next patch release of SAMSON.

This is going to be so cool. It will allow me to make parts so much faster, and parts can be made larger than in NE1. Perhaps Z88 would make a good extension to do exciting stuff with meshes inside SAMSON. https://en.wikipedia.org/wiki/Z88_FEM_software

@Jocelyn Hi, It's GNOME Shell 48.5 Thanks.

We have posted a brief tutorial on preparing protein-ligand systems with GROMACS Wizard. We will add more information to it over time, specific to each parametrization tool/server.

The groups on the SAMSON Connect website are mainly for collaboration purposes (see: User Guide: Collaboration), but they can be extended to manage licenses.

Dear @Ricardo-2 , Due to policy updates, we no longer support older versions of SAMSON and have removed them from access. Could you please tell us which features are missing for you in the latest SAMSON and which version of SAMSON you want to install?

Dear Michael, I fixed the issue in the GROMACS importers (trajectories, .gro) on macOS that was causing the options to be disabled and was also affecting the GROMACS Wizard. Could you please check whether the GROMACS Wizard and loading of GROMACS trajectories now work for you?

Hi @John-4 , In the first Python script you showed, the LLM you used (did you use Gemini or SAMSON's AI Assistant?) hallucinated and used some non-existent libraries, classes, and functions in SAMSON, which resulted in errors.

Ok, got it. SAMSON is a high priority application, so on C: it goes.

Dear @Dominic , We've just updated the Adenita extension: it now sets the nucleotide names as expected by PDB - DA, DC, DG, DT. Now, it should be suitable for export in the PDB format.

Hi @Nicolo-0 , No, currently, there is no option to specify that H-bonds in an H-bond group (which is part of a structural model) should be displayed between hydrogens and acceptors - they are drawn between donors and acceptors, since hydrogens might be implicit. However, we can add such an option in the next major release of SAMSON. But if you want it just for the sake of visualization, then you can try setting hydrogens as donors programatically (via Python). Note that this should be done without calling update() since this will recompute the bonds.

To update the topic and for information: If you are looking for instructions on how to create Python bindings for your SAMSON Extension, please refer to the Developer Guide: Creation of Python Bindings for SAMSON Extensions.

Great video, Tom! Thanks for posting it!

Thanks for sharing, Tom!
