Access Chemaxon's capabilities from KNIME workflow platform

KNIME is a user-friendly graphical workbench for the entire analysis process: data access, data transformation, initial investigation, powerful predictive analytics, visualisation and reporting. The open integration platform provides over 1000 modules (nodes), including those of the KNIME community and its extensive partner network. KNIME has been designed for general purposes, thus the basic setup contains features that are common in numerous fields. Moreover, there are plenty of cheminformatics and bioinformatics extensions which are useful especially in early phase drug discovery but can be applied anywhere chemical structure management or analysis is needed.
