Blast2tree 1.0 assists in the identification of DNA sequences from microorganisms by sending automated queries to the NCBI BLAST and GenBank databases.
In response to a sequence query, the BLAST server returns a set of similar sequences; additional information, including sequence origin and bibliographic information is retrieved from GenBank. Results from both queries are aggregated and stored for subsequent analysis. The user can then select a subset of sequences to display in a spreadsheet and include in a multiple sequence alignment and phylogenetic tree. Sequences may be filtered based on name, number of ambiguities, presence of a corresponding peer reviewed publication, length, etc. Intended for use by medical technologists, the software is now part of the daily workflow fro the sequence-based identification of bacteria and fungi in the clinical laboratory.
