NCBI 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.
Pebblescout can be used to make an index of sequence data and to search the index. Check out our preprint for additional details including the list of available indexes and examples that show the power of Pebblescout.
