SUMMARY With the advent of fully automated sample preparation robots for Hydrogen-Deuterium eXchange coupled to Mass Spectrometry (HDX-MS), this method has become paramount for ligand binding or epitope mapping screening, both in academic research and biopharmaceutical industries. However, bridging the gap between commercial HDX-MS software (for raw data interpretation) and molecular viewers (to map experiment results onto a 3D structure for biological interpretation) remains laborious and requires simple but sometimes limiting coding skills. We solved this bottleneck by developing HDX-Viewer, an open-source web-based application that facilitates and quickens HDX-MS data analysis. This user-friendly application automatically incorporates HDX-MS data from a custom template or commercial HDX-MS software in PDB files, and uploads them to an online 3D molecular viewer, thereby facilitating their visualization and biological interpretation. AVAILABILITY AND IMPLEMENTATION The HDX-Viewer web application is released under the CeCILL (http://www.cecill.info) and GNU LGPL licenses and can be found at https://masstools.ipbs.fr/hdx-viewer. The source code is available at https://github.com/david-bouyssie/hdx-viewer.

HDX-Viewer：氢-氘交换数据的交互式3D可视化。

概述随着用于氢氘交换与质谱（HDX-MS）的全自动样品制备机器人的问世，该方法已成为学术研究和生物制药行业中配体结合或表位作图筛选的最重要方法。但是，弥合商业HDX-MS软件（用于原始数据解释）和分子查看器（将实验结果映射到3D结构上以进行生物学解释）之间的差距仍然很费力，并且需要简单但有时会限制编码技能。我们通过开发HDX-Viewer解决了这一瓶颈，HDX-Viewer是一个基于Web的开源应用程序，可促进并加快HDX-MS数据分析的速度。这个用户友好的应用程序会自动将自定义模板或商业HDX-MS软件中的HDX-MS数据合并到PDB文件中，并将其上传到在线3D分子查看器，从而促进其可视化和生物学解释。可用性和实现HDX-Viewer Web应用程序是根据CeCILL（http://www.cecill.info）和GNU LGPL许可发布的，可以在https://masstools.ipbs.fr/hdx-viewer上找到。源代码位于https://github.com/david-bouyssie/hdx-viewer。
