From: An algorithm to classify homologous series within compound datasets
Examples of CH2 series containing members with cores in different positions within the molecule. Top: alcohols and ethers have the same core (C.C.O in SMILES), bottom: carboxylic acids and esters (C.C.O = CO in SMILES). Molecules are from COCONUT, and selected members from each series are shown (series_no = 597 and 662, Additional file 1: Sect. 2)
