[BLAST] (https://blast.ncbi.nlm.nih.gov/Blast.cgi) is a local alignment tool that finds similarity between sequences. This tool compares nucleotide or protein sequences to sequence databases, and calculates significance of matches. Sometimes these input sequences are large and using the command-line BLAST is required.
