In molecular modeling, a task that takes only a few minutes can become a serious drain when you repeat it across many structures, projects, or analysis steps. Repeating the same actions by hand also makes it harder to keep a workflow consistent: a missed setting or a slightly different sequence of steps can complicate comparisons later.
SAMSON’s scripting and extension tools offer two different ways to reduce that friction. Python scripting is the place to start when you want to automate work inside SAMSON or keep a scripted workflow with a document. Extensions are the route to additional capabilities, or to exploring development with the SAMSON Software Development Kit (SDK). Choosing the right route first can save you from trying to solve an automation problem by installing tools you do not need.
Start with the repeated task
Before writing a script, describe the work you want to make repeatable. Which actions do you perform more than once? What should be the same each time, and what changes between runs? This simple inventory helps distinguish a good scripting candidate from a task that depends on manual judgment.
For example, if your goal is to automate a sequence of work inside SAMSON, begin with the Scripting guide. The documentation covers the integrated Python environment, package management, running scripts, and embedding scripts or apps in documents. These are useful building blocks when you want to make a workflow easier to rerun or keep it alongside the work it supports.
A useful habit is to make the purpose of a script explicit: note what it is intended to do, what inputs it expects, and what result you want to inspect afterward. This does not replace testing, but it gives you a clearer way to check that a later run still serves the same purpose.
Keep the workflow close to the document
When a script or app belongs with a document, embedding it can help keep the workflow and the molecular work together. That can make a document more useful to your future self, or to a collaborator who needs to understand how a result was produced. Think of the document not only as a place to view molecular structures, but also as a potential home for the steps that support the work.
For repeatability, record the practical context around a scripted workflow: what it is for, which inputs need to be supplied, and what a successful result should look like. If you share the document, this context helps another person know what to run and what to verify. The scripting guide is the appropriate starting point for learning how SAMSON supports Python scripts and document-embedded workflows.
Know when extensions are the better answer
Not every need calls for Python. If you want to add capabilities to SAMSON, or learn about the SDK and extension distribution, go to Extending SAMSON. If you only use built-in capabilities and are not managing extensions, you can skip that track for now.
This distinction keeps the next step practical: choose scripting for automation and reproducible scripted workflows; choose extension management when your goal is to install or develop new capabilities. If you are exploring both, the recommended reading order is to begin with scripting and then continue to extending SAMSON.
A small plan for getting started
- Pick one repetitive task rather than trying to automate an entire project at once.
- Decide whether the need is Python automation or an additional SAMSON capability.
- Use the relevant guide to learn the supported workflow before building around assumptions.
- Keep the purpose and expected outcome clear so you can review future runs.
- When sharing scripted work, include enough context for someone else to understand its role.
Automation is most useful when it reduces repeated effort without obscuring what the workflow does. Start with one task, learn the scripting or extension path that fits it, and expand only when you have a clear reason to do so. For the overview and links to both tracks, see Automate and extend.
