Progress on an open source computer-assisted structure elucidation suite (SENECA)

We suggested and developed various components for Computer-Assisted Structure Elucidation (CASE) over the years [1, 2]. Our current goal is to integrate these into an easy to use and efficient platform for end users, called SENECA. This is based on Bioclipse [3], an integrated software suite for chemo- and bioinformatics providing plugins for file handling and visualisation of compounds and spectra.

The SENECA feature currently comprises the following components and algorithms:

• A deterministic structure generator suitable for small chemical spaces.

• Simulated Annealing and Genetic Algorithm for random structure walks in large spaces.

Simulation of 13C NMR spectra for ranking results.

SENECA is a Bioclipse feature, available via the update site at
