PERDIX (P rogrammed Eulerian Routing for DNA Design using X-overs) is a new, free, and open-source software package written in FORTRAN 90/95 that automates the conversion of 2D computer-generated design files into DNA sequences. These sequences can then be synthesized and mixed to create high-fidelity folded structures based on DNA DX in a 2D lattice framework. The software features a pure Fortran library designed for automated sequence design with support for the GEO (PERDIX's geometric file format) or other input formats for precise edge-length designs of asymmetric and irregular shapes. It provides an intuitive text-based user interface (TUI) suitable for Microsoft Windows and Mac OS, offering 24 predefined target geometric shapes for editing stapled paths and sequences with 3D visual output.
