Herein, we propose deSPI, a novel read classification method that classifies reads by recognizing and analyzing the matches between reads and reference with de Bruijn graph-based lightweight reference indexing. deSPI has faster speed with relatively small memory footprint, meanwhile, it can also achieve higher or similar sensitivity and accuracy.Availability the C++ source code of deSPI is available at https://github.com/hitbc/deSPIContact ydwang{at}hit.edu.cnSupplementary information Supplementary data are available at Bioinformatics online. %U https://www.biorxiv.org/content/biorxiv/early/2016/10/12/080200.full.pdf
