Have you ever needed to install an older version of software but struggled to navigate the process? If you’re working in molecular modeling with SAMSON and find yourself needing a specific previous release, here’s a step-by-step guide to make it easy to get the version you want.
Installing older versions of SAMSON is straightforward, thanks to built-in options in the installer. Below, we’ll walk you through the process and provide helpful insights for choosing the right version for your needs.
Step-by-Step Guide to Installing an Older Version
If you already have the SAMSON installer, follow these steps:
- Run the SAMSON Installer: Start the installation process as usual. During the initial steps, you will be prompted with various installation options.
- Enable the “Install an older version” option: This setting appears in the second step of the installer. Simply check the box labeled “Install an older version”. Below is an example image showcasing this option:
- Select your desired version: In the subsequent step, you’ll see a list of available versions labeled with their developer version numbers. Choose the version you need. Note that version numbers like 2.0.2 align with specific release years (e.g., the 2021 version of SAMSON). Refer to the documentation on User Guides for other SAMSON versions to confirm the corresponding numbers.
- Complete the installation: Continue the installation process as directed. Once complete, the selected version of SAMSON will be installed on your system.
Running Multiple Versions of SAMSON
If you have multiple versions of SAMSON installed and need to run a specific one, here are the locations of the SAMSON executables based on your operating system:
- On Windows:
C:/Users/%USERNAME%/OneAngstrom/SAMSON-Application/[Version]/Binaries/SAMSON-Core.exe - On macOS:
$HOME/Applications/SAMSON.app/ - On Linux:
$HOME/OneAngstrom/SAMSON-Application/[Version]/Binaries/SAMSON-Core.sh
Replace [Version] with the specific version number you wish to use.
Why Install an Older Version?
There are several scenarios where using an older version of SAMSON might be useful:
- Project compatibility: If you’re collaborating with others using a specific version or working with legacy files, older versions might ensure consistency.
- Extension availability: Some SAMSON Extensions might have been explicitly designed for a particular version, making them incompatible with the latest release.
- Preference: You might find certain features or behaviors in older versions align better with your workflow.
By allowing users to install older versions, SAMSON provides flexibility for diverse needs and workflows in molecular modeling.
