User-Friendly Workflows in Quantum Chemistry

Quantum chemical workflows can be built up within the science gateway MoSGrid (Molecular Simulation Grid). Complex workflows required by the endusers are dissected into smaller workflows which can be combined freely to larger meta-workflows. General quantum chemical workflows are described here as well as the real use case of a spectroscopic analysis resulting in an enduser desired meta-workflow. All workflow features are implemented via WS-PGRADE and submitted to UNICORE. The workflows are stored in the MoSGrid repository and ported to the SHIWA repository.
