BlastXtract2: Improving early exploration of (meta) genomes

To manage and intelligently mine the avalanche of genomic sequences intuitive and user-friendly graphical interfaces are required. Here we present BlastXtract2 which exclusively facilitates early exploration of un-annotated genomic and metagenomic sequences. Various formats of translated searches, including the commonly used BlastX, of multiple sequences against multiple protein databases can be uploaded to a relational database server, which can be accessed via a locally installed web-server. There, an intuitive GUI allows straightforward data-mining and enables quick detection of potential frameshifts and poorly sequenced or assembled regions, thereby contributing in making BlastXtract2 a unique and valuable tool for early exploration of (meta)genomic sequences.
