Legogen is a tool for converting CAD models into DNA nanostructures through the DNA brick method. It provides .pdb and psf files for all-atom molecular dynamics simulations in NAMD, as well as a list of nucleotide sequences for use in experiments. The tool also outputs the coordinates of DNA brick units, called voxels, and a Residue Map file (.resmap) that can be used to build subsequent structures from the same strand library. CAD models can be made inside the Legogen tool with the included 3D graphics software, Blender.
Current Version: 1.1.0
List of Changes
-Public Beta. If you have any questions or find a bug please let us know.
-Can build structures using included templates or manually.
-Included residue Map based on original DNA brick paper
