ContaBase

A contaminant database, ContaBase have been established, to allow fast MR-based screening of crystallographic data against currently 62 known contaminants. The web-based ContaMiner currently produces results in 5 min to 4 h. The program is also available in a github repository and can be installed locally. ContaMiner enables screening of novel crystals at synchrotron beamlines. Thus, in addition to potentially saving X-ray crystallographers much time and effort, ContaMiner might considerably lower the risk of publishing erroneous data.现已建立污染物数据库ContaBase，用于开展基于分子置换（Molecular Replacement，MR）的晶体学数据快速筛查，当前可针对62种已知污染物进行比对筛查。当前基于网页的ContaMiner工具可在5分钟至4小时内生成筛查结果。该程序同时托管于GitHub代码仓库，支持本地安装部署。ContaMiner可在同步辐射光束线站实现新型晶体的筛查工作。因此，该工具不仅可为X射线晶体学家节省大量时间与精力，还可显著降低发布错误晶体学数据的风险。
