Simplify Your Work: Import DNA Origami Designs into Adenita

Designing DNA nanostructures from scratch can be a daunting task, especially when you’re just getting started with molecular modeling. Whether you’re prototyping or running simulations, leveraging existing structures instead of building everything from the ground up can save you time and effort. Adenita, an extension of the SAMSON platform, allows you to seamlessly import pre-existing DNA origami designs, edit them, and prepare them for advanced workflows. Here’s how you can take advantage of this feature to streamline your molecular design process.

Why Import Existing Designs?

Reusing proven DNA designs from the community or your past projects is not only efficient but also a way to learn from established workflows. Starting from well-documented DNA origami structures can help you:

  • Learn from published examples and adapt them to your needs.
  • Reuse common structural motifs such as crossover junctions or lattices.
  • Test your modeling, editing, and simulation pipelines using known designs.

Let’s dive into the details of importing DNA nanostructures into Adenita through its user-friendly interface.

What Formats Can You Import?

Adenita supports several key formats for importing DNA origami structures, ensuring compatibility with widely-used design tools. Supported formats include:

  • .json format from caDNAno, a tool for designing DNA origami.
  • .adnpart or .adn formats, which are custom Adenita file structures.
  • .ply mesh files, which can be converted into nanostructures using the Daedalus algorithm.

This flexibility means you can start your design work with ready-to-use designs and focus on optimizing and customizing them.

Where to Find DNA Origami Designs?

If you don’t already have a design in mind, you can explore online resources that house reusable DNA origami designs. Some useful options include:

  • Nanobase, a repository for DNA, RNA, and hybrid nanostructures. It includes detailed structures, images, and oxDNA files for simulation workflows.
  • oxDNA.org example files, ready-to-use topology and configuration files for simulation tests.
  • The caDNAno Repository, a collection of caDNAno designs recreated from research articles. Remember to verify these with the associated publications before proceeding with critical projects.

You can also explore and download components directly from the SAMSON Connect Shared Documents section. For examples, check out the DNA crossover motifs and reusable designs provided by Tom Moore on his SAMSON Connect page.

How to Import Designs in Adenita

The process is straightforward. Follow these steps once you have the desired file:

  1. Open Adenita in SAMSON via Home > Apps or by using the Find Everything… tool.
  2. Click the Load Load button on Adenita’s main interface.
  3. Select your desired file format—.json, .adnpart, .adn, or .ply.
  4. The imported structure will appear in your workspace for inspection, editing, and modification.

Once imported, you can augment the design using Adenita’s handy editing tools or prepare it for simulations.
