**pyFuRNAce** is an open-source Python package and web-based design engine for creating complex RNA nanostructures using the co-transcriptional RNA origami approach. It streamlines the entire design pipeline — from structural motif assembly to sequence generation and primer design — into an intuitive, user-friendly platform.

## 🚀 Features

- 🧩 **Motif-based assembly:** Build RNA structures using a rich, expandable library of motifs including stems, dovetails, kissing loops, aptamers, and ribozymes.
- 🎨 **GUI & Real-time 3D Visualization:** Interactive blueprint editor and real-time 3D rendering via Streamlit and oxView.
- 🔄 **Integrated Workflow:** Design, generate, convert, and prepare your RNA origami in one unified interface.
- 🧬 **Sequence Generation & Optimization:** Built-in support for sequence folding (Revolvr + ViennaRNA).
- 🧪 **Primer & Template Design:** Includes tools for DNA conversion, promoter addition, and primer calculations.
- 💻 **Python Scripting API:** Automate complex designs or build at scale using a programmable interface.

### System requirements

- Python 3.10 or later
- Operating System: Linux, macOS, or Windows
- dependencies are listed in `requirements.txt`; with stable versions recommended in `stable_requirements.txt`

## 📦 Installation

Typical installation time: 5 minutes

### Pyfurnace

Note: pyFuRNAce requires Python 3.10 or later, and the local installation always includes the GUI via Streamlit.

#### Install from PyPI
Install or upgrade the latest stable version of pyFuRNAce from PyPI using pip (and OAT from GitHub):

```bash
pip install --upgrade pyfurnace
```

#### Install from GitHub
Install the latest development version of pyFuRNAce (and OAT) directly from the GitHub repository:

```bash
pip install "git+https://github.com/Biophysical-Engineering-Group/pyFuRNAce.git"
```

### Extra Dependencies

**Note**: The **pyFuRNAce installation does not include the oxDNA analysis tools (OAT)**.

The OAT package is used to convert 3D structures from/to PDB files and write oxDNA force files.
To install the OAT package, you can use the following command (the **git** command is required, you can install it via anaconda with `conda install git`):

```bash
pip install "git+https://github.com/lorenzo-rovigatti/oxDNA.git#subdirectory=analysis"
```

To run sequence generation, a `Perl` interpreter is required by the Revolvr script from ROAD. It is usually installed by default on most systems. If not, you can install it via Anaconda with `conda install bioconda-legacy::perl`.

## 🖥️ Running the Web Application

To run the web application locally after installation, use the following command:

```bash
pyfurnace
```

Or alternatively `python -m pyfurnace`.

This will lunch the GUI in your default web browser.
You can also use the hosted version at [pyfurnace.de](http://pyfurnace.de).
The WebApp is built using Streamlit and can be run locally or on a server. You can access the webapp directly at
[pyfurnace.streamlit.app](https://pyfurnace.streamlit.app).

[![Streamlit App](https://static.streamlit.io/badges/streamlit_badge_black_white.svg)](https://pyfurnace.streamlit.app/)

## 🎛 Modules

1. Design: Create and edit RNA structure blueprints. Visualize assembled structures in 3D.
Define custom motifs via GUI or scripting.
2. Generate: use inverse folding (Revolvr) to produce RNA sequences matching the target structure. Evaluate folding energies and structural ensemble diversity.
3. Convert: Translate RNA sequences to DNA templates. Add transcriptional promoters (e.g., T7). Analyze sequence properties (e.g., GC content, dimers).
4. Prepare: Design PCR primers with melting temperature calculations. Generate input files for molecular dynamics simulations with oxRNA.

## 🧑‍💻 Using the Python API

```python
import pyfurnace as pf

line1 = [pf.TetraLoop(),
        pf.Stem(7),
        pf.Dovetail(-2, up_cross=False),
        pf.Stem(6),
        pf.KissingDimer(),
        pf.Stem(6),
        pf.Dovetail(-2, up_cross=False),
        pf.Stem(7),
        pf.TetraLoop(True),
        ]

line2 = [pf.TetraLoop(),
        pf.Stem(7),
        pf.Dovetail(-2, down_cross=False),
        pf.Stem(10),
        pf.start_end_stem(),
        pf.Stem(10),
        pf.Dovetail(-2, down_cross=False),
        pf.Stem(7),
        pf.TetraLoop(True),
        ]

origami = pf.Origami(line1, line2, aling='center')

print(origami)
print(origami.structure)
print(origami.sequence)
```
