XspecT 0.4.1

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 kmer indices 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.

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