The National Center for Biotechnology Information is excited to introduce Pebblescout, a pilot web service that allows you to search for sequence matches in very large nucleotide databases, such as runs in the NIH Sequence Read Archive (SRA) and assemblies for whole genome shotgun sequencing projects in Genbank – faster and more efficiently!  

Pebblescout uses short segments of your query sequences to identify database records with matches. Matches are based on the frequency of a segment’s occurrence in a database. Result produced for each query is a ranked list of matching records where the ranking utilizes informativeness of matching segments.
