SAMSON crashes while opening pdb files
-
Whenever I open pdb files on my laptop while using SAMSON, the application causes the crashes of my graphic card driver. I have the ATI Mobility Radeon 550v graphic card with OpenGL version 6.14.10.9833. Concurrently I am using Autodock Tools 1.5.6. suite and it works properly, while performing docking of small molecules into protein structures. Can you solve my problems with SAMSON?

Hello, sorry about that. Could you please give us some information about your OS? Do you see the blue background in the viewport? Could you please do the following test:
- press A to select the "Atom creator" editor (or go to "Edit / Editors / Atom creator")
- click somewhere in the viewport to add an atom.
Thanks,
S.

My OS is Windows 7 SP1 64-bit, my computer is Dell Inspiron M5010. Yes, I can see the blue background. I did the test - the same effect: my graphic card crashed (info: Samson caused AMD driver of graphic card to stop working, but after a while it got recovered).

I found this on SAMSON Documentation webpage (https://documentation.samson-connect.net/users/latest/user_guide_getting_started.html):
"Requirements
For running SAMSON, a 64-bit operating system and a graphics card supporting OpenGL 3.2 are required. Intel graphics cards may currently cause issues. For NVIDIA and AMD graphics cards an appropriate driver with an OpenGL support should be installed."
Should I install this driver? I have a higher version of OpenGL (6.14.10.9833). I am confused (AMD is the manufacturer of my graphic card). -
Ok thanks. Maybe it is possible to upgrade to the latest version of your graphics card driver? Is it possible to deactive most rendering options in the preferences?
- No ambient occlusion, no depth-of-field, no fog, no silhouettes, no shadows
- In Selection: 0% opacities
- Anti-aliasing: multisampling factor to 1, disable FXAA
Please let me know.
Thanks,

Dear @Radek
The version 6.14.10.9833 you are referring to is no the version of OpenGL but it is the version of your ATI OpenGL driver. Please, check whether your driver has OpenGL 3.2 or higher. And try updating your driver if possible.
As I can see, your GPU should support OpenGL 3.3 but I am not sure about your driver.

Dear @DmitriyMarin
I am sorry, I have no idea how to check OpenGL. I thougt the info about this is within the application controlling the graphic card. If not - I do not know how to find it.

To check on Windows the OpenGL support of your GPU, you can, for example, install OpenGL Extensions Viewer. It should show you what version of OpenGL does your GPU support and, possibly, the version provided with your current driver.
If you have the most recent driver for your ATI Mobility Radeon 550v GPU, then, I think, it should support OpenGL 3.3, since it is this version which is supported by your GPU.

Thank you. Within the info about my graphic card driver it is specified that it supports OpenGL 3.3. Anyway I cannot use SAMSON on my computer. For some reasons it causes the crashes of my graphic card. Thank you for your support, but I am unable to solve the problem. I use different similar programs without any problems (Auto Dock, Chimera, PyMOL etc.).

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.
