Rdkit fingerprint similarity

WebThe similarity measures usually consider the number of positive bits (1’s) present in either fingerprint and the number of positive bits that both have in common. Dice similarity usually returns higher values than Tanimoto similarity because of their denominators: c a + b − c ≤ c 1 2 ( a + b) Virtual screening WebAug 14, 2024 · RDKitでフィンガープリントを使った分子類似性の判定. pythonの代表的なケモインフォマティクスライブラリである RDKit を用いて,これまで本ブログでは化合物の性質を表現するための分子記述子について学んできました.. など化合物の 物性や性質 に関連 ...
