Dear @Oisin ,

Covalent bonds are created based on the interatomic distances. Maybe the atoms are placed too far from each other? Could you please check the distance between atoms in your system - you can do it using the Measure editor by clicking on two atoms consecutively. Could you please attach a .cif file in which you experience the problem such that we could check it.

By the way, are you referring to .cif for biomolecules (mmcif/PDBx format) or .cif for crystals?

Dear Martin,

Thanks for your feedback. It appears you’re on a very specific machine as most users install SAMSON within minutes without any issues on Windows Linux or Mac in standard directories. Please contact the developers at contact@samson-connect.net as indicated in the automated email you received about installation.

We’re happy you think SAMSON is looking good too :).

Best

@aaa Thank you for reporting your solution here!

Hello, could you please tell us which graphics card you have? This seems to indicate a GPU issue.

Hello,

The issue is that SAMSON was installed as Administor. Can you please try to activate User Access Control (UAC) so that Windows does not install SAMSON as admin? Here's a link about how to do that: https://www.technipages.com/windows-enable-disable-user-account-control-uac

Please set UAC to e.g. "Always notify" (you can set it back to the previous setting afterwards).

Then, please restart your computer, and install SAMSON again.

Please let me know how this goes.

Thanks,

Stephane

Hello @Prokop ,

To connect two atoms with a bond, use the Add editor: press on the first atom and draw a bond to the second one and then release. Please see the gif below:

@shozeb Here is the process to uninstall SAMSON :

delete : rm -rf ~/.local/share/OneAngstrom/
delete : rm -rf ~/OneAngstrom/
delete : rm -rf ~/Documents/OneAngstrom/
delete : rm -rf ~/.config/OneAngstrom/
delete : rm -rf ~/.config/NANO-D (if exists)

After that you may try to reinstall SAMSON as described in the documentation.

Don't hesitate to contact us again if the issue is not solved. Users are our priority.

Dear @Tadija
This just means that SAMSON was not able to get the name of the GPU but it should have detected it properly. Does SAMSON work properly for you or you experience some problems with graphics?

Dear @Radoslaw ,
We have fixed an issue in SAMSON which was causing a problem with OpenGL context on Intel integrated graphics processors. We hope it might as well resolve the issue you had and we would be grateful if you could try re-installing SAMSON to check whether it fixes it.

Dear @Ivan ,
Thanks to issues raised on the forum, we have fixed the issue in SAMSON causing problems with the viewport when using Intel integrated graphics processor. This issue might have been causing the problem you have posted in this thread. The new installation of SAMSON should resolve the issue.

Hello @Robert ,
Thanks to your feedback, we have fixed the issue in SAMSON when using Intel integrated graphics processor. You can try installing SAMSON.

Installation is done.

Hello, could you please contact us by email (please reply to the registration email) so we can see what we can do?
