How to Import and Reuse DNA Nanostructures in Adenita

When designing DNA nanostructures, starting from scratch can be overwhelming and time-consuming. The ability to import and reuse existing designs is a game-changer for researchers and modelers who aim to save time or learn from published work. Let’s explore how you can import DNA nanostructures efficiently using Adenita in the SAMSON molecular design platform.

Why Import DNA Nanostructures?

Reusing pre-designed DNA structures offers several advantages:

  • Learning: Study and replicate examples from established research.
  • Simplification: Avoid building motifs or structures that have already been designed.
  • Testing: Evaluate Adenita’s workflows for import, editing, and simulation by using existing designs.
  • Combining: Seamlessly integrate multiple structures to create more complex systems.

Supported File Formats

Adenita supports a variety of commonly used formats in DNA nanotechnology, including:

  • .json files for designs created in caDNAno.
  • Adenita’s own component files, such as .adnpart and .adn, suitable for saving and reusing individual components or complete designs.
  • Exports to oxDNA format for coarse-grained simulations.

This diversity allows users to integrate workflows and tools conveniently into their research pipelines.

Where to Find Reusable DNA Nanostructures

Pre-existing DNA origami designs are readily available from a variety of sources:

  • Nanobase — A public repository containing DNA, RNA, and hybrid nanostructures, including original design files and oxDNA files ready for use.
  • oxDNA.org example files — Ready-to-use topology and configuration files for testing oxDNA workflows.
  • The caDNAno Repository — A community-driven collection of caDNAno .json designs based on published research articles.
  • SAMSON Connect > Shared Documents — Including many example components, such as those shared by Tom Moore, like crossovers and mechanical motifs.

Through these resources, you can find various components or structures to adapt or integrate into your projects.

How to Import in Adenita

The process of importing DNA designs in Adenita is straightforward:

  1. Open the Adenita interface via Home > Apps or Find everything….
  2. Use the Load Load function in the main interface to choose your file. Supported formats include .json, .adnpart, and .adn files.
  3. For additional components, continue loading files into the same workspace.

You can now inspect, edit, or combine imported structures as your project demands!

Considerations Before Reusing Designs

When utilizing external designs, there are certain points to remember:

  • Validate designs where necessary, especially if sourced from repositories (e.g., those in the caDNAno Repository).
  • Check for licenses, citation requirements, or related publication constraints.
  • Test the compatibility with your intended workflows or tools (e.g., simulation software).

Next Steps

Once your structure is loaded and edited, you can take full advantage of Adenita’s export functions. Export the design as oxDNA files for simulation workflows or save it in formats for ongoing projects.
