We introduce $\textit{scadnano}$ (https://scadnano.org) (short for "scriptable cadnano"), a computational tool for designing synthetic DNA structures. Its design is based heavily on cadnano, the most widely-used software for designing DNA origami, with three main differences: 1. scadnano runs entirely in the browser, with $\textit{no software installation}$ required. 2. scadnano designs, while they can be edited manually, can also be created and edited by a $\textit{well-documented Python scripting library}$, to help automate tedious tasks. 3. The scadnano file format is $\textit{easily human-readable}$. This goal is closely aligned with the scripting library, intended to be helpful when debugging scripts or interfacing with other software. The format is also somewhat more expressive than that of cadnano, able to describe a broader range of DNA structures than just DNA origami.

scadnano：一种基于浏览器的、可编写脚本的工具，用于设计 DNA 纳米结构

我们介绍了 $\textit{scadnano}$ (https://scadnano.org)（“scriptable cadnano”的缩写），这是一种用于设计合成 DNA 结构的计算工具。它的设计主要基于cadnano，这是最广泛使用的DNA折纸设计软件，主要有以下三个区别： 1. scadnano 完全在浏览器中运行，不需要$\textit{无需安装软件}$。2. scadnano 设计，虽然它们可以手动编辑，但也可以通过 $\textit{well-documented Python scripting library}$ 创建和编辑，以帮助自动化繁琐的任务。3. scadnano 文件格式为 $\textit{易读}$。此目标与脚本库密切相关，旨在在调试脚本或与其他软件交互时提供帮助。格式也比cadnano更具表现力，
