老师好,
我是复旦大学向红军课题组的陈奕舟。
最近我希望使用HPCSD数据库,网页端的数据库非常有帮助,但我在测试时发现,目前通过网页API可访问的数据量仅为1.4万条,而非论文中所提及的66,353个。
想请教一下:我想申请获取HPCSD的完整数据集,主要是晶体结构,可否提供?如需要提供用途说明或其他信息,请告知于我,我都可以配合。
万般感谢。
陈奕舟

Dear CALYPSO/HPCSD team,
I am Yizhou Chen from Prof. Hongjun Xiang's group at Fudan University.
I would like to use the HPCSD database for my research. The web database is very helpful, but during my tests I found that the data accessible through the web API contains only about 14k records, rather than the 66,353 records mentioned in the paper.
May I ask whether it would be possible to obtain the complete HPCSD dataset, mainly the crystal structures? If a statement of intended use or any other information is required, please let me know. I would be happy to provide it.
Best regards,
Yizhou Chen

奕舟您好,

感谢您对 CALYPSO 高压晶体结构数据库 HPCSD 的关注。

在论文中,我们提到数据库数据主要包括两部分:单质数据 10,993 条,以及 CALYPSO 社区收集的数据 66,353 条,共计 77,346 个条目。近期我们仍在持续扩充数据库规模,目前数据条目数应已达到 151,976 条。因此,您提到的 1.4 万条目可能存在误解。

目前,HPCSD 的 API 接口仍在开发中,暂不支持批量下载。不过,在每个结构的详情页面,我们均提供了优化后结构文件的下载按钮,您可以按需下载。

如您这边确有获取全部数据的需求,建议请向老师与王彦超老师进一步沟通联系。

祝好!

王振雨

王老师您好!

感谢您于工作繁忙中拨冗回复。

经过确认,能访问的数据总量确为151,976条,我前述14k条系有误。给您的工作造成烦扰,深感歉意。

深切期待HPCSD的API接口开放,祝愿CALYPSO项目取得更大进展。

顺颂时祺

陈奕舟
