WebThe RDKit can generate conformations for molecules using two different methods. The original method used distance geometry. [1] The algorithm followed is: The molecule’s distance bounds matrix is calculated based on the connection table and a set of rules. The bounds matrix is smoothed using a triangle-bounds smoothing algorithm. WebThese methods return fingerprints as lists of features and can be used with the tc method to calculate the Tanimoto coefficient. The distribution models are obtained from the stats objects using the get_tc_distribution methods. The method takes a fingerprint as an optional parameter to obtain the conditional models. import rdkit.
