In particular, SEQenv is a pipeline aiming at annotating 16S rRNA and metagenomics microbial sequences based on environment descriptive terms.
Sequence similarity searches against public databases and the recognition of terms such as “glacier, pelagic, forest, lagoon” (i.e. Environment Ontology terms identified by the ENVIRONMENTS tagger) within Genbank records (e.g. “isolation source" field) and/or in the relevant literature (PubMed abstracts) are being employed to characterize novel microbial sequences. Subsequently, a range of visualizations, such as tag clouds, heatmaps, are generated to describe OTUs and samples.
Built incrementally, in three hackathons since September 2012, several features were added to SEQenv. e.g. starting from 16S rRNA sequences the pipeline now may be invoked either a. for DNA sequences or b. for protein sequences.
The effort and devotion of all participants (see image above) was the driving force overcoming the long-hours and any technical difficulties that arose. A big thank you from the organizers (without forgetting the SEQenvI and SEQenvII participants).
All three SEQenv hackathons have been funded by the EU COST ES 1103 Action on "Microbial ecology & the earth system: collaborating for insight and success with the new generation of sequencing tools".
Any software produced during the hackathon will be made available as open source.
