一、RDkit访问分子的性质,并输出到一个SDF文件中 RDkit支持通过sdf、mol等文件形式输入化合物信息,也可以将文件输出为sdf、mol等文件,在以下代码示例中,我们将从一个smile分子式列表中读取分子,并将化合物信息输出到工作目录下的/files/batch.sdf文件中。在RDkit中,用描述符(Descriptors)来表达分子性质。在如下示例...

Molecules which come from Mol or SDF files will now always have the "_MolFileChiralFlag" property set to the value of the chiral flag in the CTAB. In previous versions the property was not set if the chiral flag was 0. Bug Fixes: GetSubstructMatches uniquify and maxMatches don't work ...
RDKit提供各种功能,如不同的化学I/O格式,包括SMILES/SMARTS,结构数据格式(SDF),Thor数据树(TDT),Sybyl线符号(SLN),Corina mol2和蛋白质数据库(PDB)。子结构搜索; 标准SMILES; 手性支持;化学转化;化学反应;分子序列化;相似性/多样性选择;二维药效团;分层子图/片段分析; Bemis和Murcko骨架;逆合成组合分析程序(REC...
