A special emphasis is given to graph clustering, allowing users to scrutinize target contexts for ligand candidates. We show how GAPIN can be used to unveil underlying hydrophobic patterns on a set of peptidase-inhibitor complexes. In another experiment, we show there is a positive correlation between cluster sizes and the presence of druggable spots, indicating that the clustering may discriminate the higher complexity of these hot subnetworks.Availability and implementation GAPIN is freely available as an easy-to-use web interface at https://gapin.unifei.edu.br.Contact biharck{at}ufmg.br, carlos.silveira{at}unifei.edu.br.Supplementary information Supplementary data are available online.
