Rdkit generate 3d conformations
Webrdkit's 3d coord generation algorithm was designed for small- to medium-sized "druglike" molecules, so you may expect it to fail in areas very far from this territory. For example, it does not work well for long conjugated oligomers - sometimes it produces molecular knots instead of straight strands, and is quite slow for large systems. WebApr 21, 2024 · The “recovered” column in Table 3 shows that vacuum conformer-rotamer ensembles (CREs) were generated for over 98% of the molecules in each dataset other than SIDER. CREST CREs were also generated...
