PLAST is a parallel alignment search tool for comparing large protein banks. PLAST runs 3 to 5 times faster than the NCBI-BLAST software when processing large amount of data.

The following features are currently available:

  • Protein vs protein (plastp), protein vs nucleotide (tplastn),

nucleotide vs protein (plastx) and nucleotide vs nucleotide (tplastx) searches.

  • Query filtering using SEG low complexity filters.
  • Karlin-Altschul alignment statistics.
  • Composition-based score adjustments as in Bioinformatics 21:902-911

for plastp and tplastn.
