Collection

Nowadays data linked to research in particular in the biological domain is made available in public repositories. In particular, the NCBI sequence read archive (SRA) repository provides raw high-throughput sequencing (HTS) data generated for specific studies of interest. This archive contains many studies which belong to metabarcoding and it is a very valuable source of information. Unfortunately, biological information from sequence data contained in these studies is not directly retrievable. 

The data made available in SRA derives always from a publication. Researchers find it difficult nowadays to explore and select data which is contained in different repositories. Also there seems to still be missing the cross reference of the main repositories such as PubMed and Sequence Read Archives. 

The MDDB allows to navigate and search within the main descriptions of a publication and of a study containing the sequence data. The web interface is designed to search within the provenance identifiers of the repositories, but also by using keywords linked to the title, abstract, authors and institution both within the domain spaces of literature and SRA repositories.
