XspecT 0.2.7

Tool to monitor and characterize pathogens using Bloom filters.

XspecT - Acinetobacter Species Assignment Tool

XspecT is a Python-based tool to taxonomically classify sequence-reads (or assembled genomes) on the species and/or MLST level using Bloom Filters and a Support Vector Machine.

XspecT utilizes the uniqueness of kmers and compares extracted kmers from the input-data to a reference database. Bloom Filter ensure a fast lookup in this process. For a final prediction the results are classified using a Support Vector Machine.

Local extensions of the reference database are supported.

The tool is available as a web-based application and a smaller command line interface.
