Creating a Nano-Batarang with Simple Script in SAMSON

If you’ve ever wondered how to merge creativity with molecular modeling, turning a nanoscale structure into something as iconic as Batman’s batarang might be what you’re looking for. While a nano-batarang is unlikely to fight viruses or tumors, it is an incredibly engaging way to discover how atom selection and manipulation work in SAMSON using its Simple Script Extension.

Why Build a Nano-Batarang?

Molecular modeling often involves selecting atoms and modifying their properties with precision. However, the steep learning curve of scripting languages used for this can deter many potential users. By creating a structure as recognizable and fun as a batarang, you can grasp atom selection, coordinate transformations, and property manipulations—key skills in molecular design—without feeling overwhelmed. The humor and joy of crafting a nano-batarang make technical concepts easier to digest.

What Makes the Simple Script Extension Special?

The Simple Script Extension in SAMSON allows you to programmatically select and modify atoms within a molecular structure interactively and in real-time. It supports predefined variables, operators, logic, and even trigonometric functions. You can directly alter atom positions, visibility, and other attributes using flexible scripts, making this an excellent starting point for molecular modeling beginners.

How to Create Batman’s Nano-Batarang

To get started, you’ll first need to place a graphene sheet in the z-plane. This structure will serve as the “canvas” for cutting out the batarang shape. Using the provided script in the documentation, you’ll rely on mathematical conditionals and loops to define the iconic shape of Batman’s logo. The script iteratively evaluates whether each atom in the graphene sheet falls within the complex mathematical geometries defined by multiple regions (like the wings, head, and ears) of the logo.

Here’s the general idea:

Use variables like a.x and a.y to access and manipulate atom coordinates.
Implement conditional structures to define the visible and invisible regions of the structure.
Tweak parameters and boundaries to refine the cuts in the graphene sheet until it perfectly resembles the batarang.

The script can also include functions for inequalities, trigonometric calculations, and even logical evaluation to manage more nuanced design aspects. A simple example shows how visibility and selection flags (a.vf and n.sf) determine which atoms remain in the final shape:

    if (a.x^2 + a.y^2 < certain_value) {
      a.vf := 1;
    } else {
      a.vf := 0;
    }

						    if (a.x^2 + a.y^2 < certain_value) {
      a.vf := 1;
    } else {
      a.vf := 0;
    }

					

			

For Batman’s iconic logo, the logic is slightly more involved but demonstrates just how much detail you can achieve through this approach.
