Projects / JOELib/JOELib2


JOELib/JOELib2 is a cheminformatics library which supports SMARTS substructure search, descriptor calculation, processing/filtering pipes, and conversion of different chemical file formats. It is written in 100% pure Java, and interfaces to external programs (e.g. Ghemical) are available.

          Release Notes: This release allows the user to switch off the automatic aromaticity check and assignment. This allows using query input structures without complete aromatic systems. Several minor bugs were fixed.
