Editing, validating and translating of SBGN maps

Motivation: The recently proposed Systems Biology Graphical Notation (SBGN) provides a standard for the visual representation of biochemical and cellular processes. It aims to support more efficient and accurate communication of biological knowledge between different research communities in the life sciences. However, to increase the use of SBGN, tools for editing, validating, and translating SBGN maps are desirable. Results: We present SBGN-ED, a tool which allows to create all three types of SBGN maps from scratch or edit existing maps, to validate these maps for syntactical and semantical correctness, to translate networks from the KEGG and MetaCrop databases into SBGN, and to export SBGN maps into several file and image formats. Availability: SBGN-ED is freely available fro
