G. Roewer,U. Herzog,K. Trommer,E. Müller,S. FrühaufWe describe our work on the following three topics: (i) geometric data structures for representing and manipulating molecules; (ii) conformational analysis—searching for low-energy conformations; and (iii) pharmacophore identification—searching for common features among different ligands that exhibit similar activity.
