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

Awesome, you're welcome! Happy designing!

Thanks. This strongly suggests that the runtime was not installed correctly: vcruntime140_1.dll cannot be found. Please download it from the site indicated in the module description. The direct link is https://aka.ms/vs/16/release/vc_redist.x64.exe.

This does not seem to be the correct folder. You should not go to C:\Users\hpnk9\OneAngstrom but to C:\Users\hpnk9\AppData\Local\OneAngstrom\SAMSON-Data\0.8.5\Scratch\Elements\DDA2A078-1AB6-96BA-0D14-EE1717632D7A. Note that AppData might be hidden, so you might have to show them in explorer settings. (You could also directly copy-paste this path in the explorer).

Hello, is this Windows 7? 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.dummies.com/computers/computer-networking/using-a-network/how-to-change-user-account-control-settings-in-windows-7/

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

You will probably have to restart your computer. Then, you should reinstall SAMSON.

Please let me know how this goes.

Thanks,

Stephane

Hi @Phuong, could you please analyze the dependencies of the module on your computer?
Here's how to do it:

• download the Dependencies tool from https://github.com/lucasg/Dependencies/releases/download/v1.10/Dependencies_x64_Release.zip
• unzip everything in a folder
• run DependenciesGUI.exe
• With the DependenciesGUI tool, open the file C:\Users\ [Your user name] \AppData\Local\OneAngstrom\SAMSON-Data\0.8.5\Scratch\Elements\DDA2A078-1AB6-96BA-0D14-EE1717632D7A\DDA2A078-1AB6-96BA-0D14-EE1717632D7A.dll

Could you please report which dlls appear to be missing?

Thanks,

Stephane

Thanks Ibrahima! Let us know if we can help in any way.

Dear John,

Thanks for your interest in SAMSON. please note that, to use Adenita, you will need to install an older version than the current one (e.g. 0.8.5) (there’s a checkbox for this in the installer) since this module is not yet available for SAMSON 2020.

Best,

Stephane

Hello Emmanuel! We were actually talking about you just a few hours ago because we saw your posts about your VR class! It's awesome!

You can actually already move molecules with one hand if you use the "Move" mode (which moves stuff) instead of the "Navigate" mode (which moves yourself).

We decided to use both hands for navigation because we wanted the user to be able to scale as well as rotate / translate the view (7 degrees of freedom), and our tests have shown that this is what is familiar to many people (who use two fingers for scaling on phones). Using both hands and spreading arms / bringing arms closer changes your scale relatively to the molecules. When you move both hands without changing the distance between them you can rotate, translate, etc. Changing the scale in an intuitive way was really important to us to address many different scales as in the virus demo. In the frame below, the user height is around 0.1 microns:

while in this frame (inside the virus) the user height is about 1 nanometer:

(sorry for the video compression blur).

To move molecules instead of yourself, you use the thumbpad in "Move mode" (the two other thumbpad modes are "Add" and "Erase"), and you choose the selection filter that corresponds to what you want to move. This way, you can move a molecule with a single hand (or two molecules with two hands).

For example, in the Selection menu, choose the selection filter called "Structural models" as in the figure below:

Depending on your structures, you might want to select other levels (e.g. molecules, chains, etc., or the default "atoms and bonds").

Then, using the thumbpad, you can rotate / translate when you press on the thumbpad. This is demonstrated e.g. in this video where the user manipulates two carbon nanotubes at the same time to stick them together during interactive simulation. Each hand independently moves each nanotube.
.

You can have different modes in each hand (e.g. Add on the left hand, Move on the right hand, etc.).

I hope this helps. I'll be happy to talk more about it, as well as about extensions and applications.

Best,

Stephane Redon

Hello, when using the installer, you can check the box "Install older versions". The next step will give you the possibility of choosing the version you want, including 0.7.
