Daedalus - software to render nearly any 3D geometry as a scaffolded DNA origami nanoparticle.

Your 3D models can be input using the Polygon File Format (.ply).

1. Clone this repo
2. (optional) Set up a virtualenv.
3. pip -r requirements in this project's root.

At the minimum when calling demo_daedalus.py, you need to tell it what ply file to run. For example, running pyDAEDALUS on the included ply file 05_icosahedron.ply can be done with the command:
python demo_daedalus.py --input_filename=PLY_Files/05_icosahedron.ply Note including the .ply extension is optional. So the following command would be equivalent: python demo_daedalus.py --input_filename=PLY_Files/05_icosahedron

You can also run a batch of ply files at a time by specifying an input foldername rather than a single ply file:
python demo_daedalus.py --input_foldername=PLY_Files

Adding the flag --display_plots asks the program, in addition to saving the plots to your output folder, to print them to screen. For example:
python demo_daedalus.py --input_filename=PLY_Files/37_enneagonal_trapezohedron.ply --display_plots

Additional options include:

• --results_foldername=yourfoldername where 'yourfoldername' is the name of the folder you want to save this command's results in. Folder will be created if it doesn't already exist.
• --suppress_console_output (flag) if you want to not have things printed to your console at runtime. (always suppressed when running a batch)
• --reset_results_folder (flag) if you want to erase all data within your output folder before running the current command.

You can find the complete list of arguments with descriptions with python demo_daedalus.py --help.

All files saved into Results includes both shape name and min_len_nt in the filename to avoid undesired filename collisions.

Testing uses py.test. Ways to run tests manually include:

• Simply run make test. This leverages Makefile to run tests with the right syntax.
• Run all tests by directly calling pytest: py.test
• Run all tests and drop into a bpython-enabled debugger at failure: py.test --bpdb
• To run a test class or stand-alone function: py.test tests/test_ply_to_input.py::test_ply_input_for_05_icosahedron
• To run a single function within a test class: py.test tests/test_ply_to_input.py::TestIntegrationsUsing01Tetrahedron::test_generate_spanning_tree

Testing coverage done with pytest-cov package. Manually run coverage report with:

• py.test --cov=Automated_Design tests/ to run coverage on folder Automated_Design using all tests found in tests folder.
• py.test --cov-report html --cov-report term --cov=Automated_Design tests/ to run coverage report as above, but with also generating a line-by-line report formatted as html (viewable in your browser by opening the created files)

The only code deliberately excluded from tests are plotting functions (e.g., ply_to_input.plot_edge_length_distributions) and functions that simply write raw internal data to disk (e.g., csv_staples). All such functions are marked to not be included in the coverage report by adding the comment # pragma: no cover on the same line as the function definition.

For convenience, Makefile is used to add several command shortcuts to do common testing operations:

• make to run both linting and tests (linting is only ran if tests pass)
• make test to run only tests.
• make lint to run only linting.
• make coverage to run coverage report. The report is returned as both top level statistics to terminal and a line-by-line report saved into folder htmlcov as html files.
