What is JCoast?

JCoast is a next-generation software solution for the exploration, mining and comparison of your genome and metagenome projects. Based on a set of predicted and automatically annotated ORFs (a genome or metagenome) it acts as a window into these preprocessed data which does not only allow to view the initial results but also facilitates improved annotation and in-depth data analysis. JCoast allows you to  "interact" with your genomic data and to turn them into biological knowledge in a straightforward way.

The JCoast features of the current release 1.6 include integration of several standard tools for genomic data analysis plus databases for similarity and HMM searches.

The JCoast release 1.0 was published in 2008 in BMC Bioinformatics. Since then it has been used/cited by several projects,  see the full list at Google Scholar.

If you have feedback or questions concerning the JCoast Project, feel free to contact us or to submit a support ticket.



The current version of JCoast is released under the GNU General Public License, as published by the Free Software Foundation version 3 of the License.

JCoast is, and will stay, absolutely free - the software is maintained by Microbial Genomics & Bioinformatics Group at the Max Planck Institute for Marine Microbiology in Bremen, Germany, in cooperation with a professional partner to assure maximum sustainability.
