DnaDesign

DnaDesign is a Go project creating tools for automated genetic design, spanning from the lowest levels of DNA sequence manipulation to higher level functionality.

• Practical: DnaDesign tooling is meant to be used by practitioners of synthetic biology.

• Modern: DnaDesign is at the bleeding edge of technology. We are happy to adopt the newest advancements in synthetic biology, wasm, LLMs, and more to get our tools in the hands of people who need it.

• Ambitious: DnaDesign's goal is to be the most complete, open, and well used collection of computational synthetic biology tools ever assembled. If you like our dream and want to support us please star this repo, request a feature, or open a pull request.

Documentation

• Python Documentation
• Go Library Documentation

Repo organization

On the highest level:

• lib contains core functionality as a go library.
• external contains functions to work with external bioinformatics command-line interfaces.
• py contains code to use the dnadesign library in python using a C shared library.

Detailed repo organization

• lib contains the core DnaDesign library, with nearly all functionality, all in idiomatic Go with nearly no dependencies.
  • lib/bio contains biological parsers for file formats including genbank, fasta, uniprot, fastq, slow5, sam, and pileup files.
  • lib/align contains Needleman-Wunsch and Smith-Waterman alignment functions, as well as the mash similarity algorithm.
  • lib/clone contains functions for simulating DNA cloning, including restriction digestion, ligation, and GoldenGate assembly.
  • lib/fold contains DNA and RNA folding simulation software, including the Zuker and LinearFold folding algorithms.
  • lib/primers contains DNA primer design functions.
    • lib/primers/pcr contains PCR simulation functions.
  • lib/seqhash contains the Seqhash algorithm to create universal identifiers for DNA/RNA/protein.
  • lib/synthesis contains various functions for designing synthetic DNA.
    • lib/synthesis/codon contains functions for working with codon tables, translating genes, and optimizing codons for expression.
    • lib/synthesis/fragment contains functions for optimal GoldenGate fragmentation.
    • lib/synthesis/fix contains functions for fixing proteins in preparation for synthesis.
  • lib/transform contains basic utility functions for transforming DNA, like reverse complementation.
• external contains integrations with external bioinformatics software, usually operating on the command line.
  • external/minimap2 contains a function for working with minimap2 with Go.
  • external/samtools contains a function for generating pileup files using samtools with Go.
  • external/bcftools contains GenerateVCF to generate a VCF file from sam alignments using bcftools with Go.

Python

We have python package, dnadesign, which allows python users to use dnadesign. This is a work-in-progress: more documentation coming soon!

Sources

There are a few pieces of "complete" software that we have directly integrated into the source tree (with their associated licenses). These projects don't receive updates anymore (or just bug fixes with years between). In particular, lib has most of these, since we intend to have as few dependencies as possible in lib. The integrated projects include the following.

• svb in lib/bio/slow5/svb
• intel-cpuid in lib/bio/slow5/svb/intel-cpuid
• wordwrap in lib/bio/genbank
• errgroup in lib/bio/

Other

DnaDesign is a fork of Poly at commit f76bf05 with a different mission focus.
