BLAST (Basic Local Alignment Search Tool) finds regions of similarity between biological sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance.
CyVerse UK provides the following BLAST applications:
- Create BLAST db, to create a database to use in one of the BLAST comparison tool.
- BLASTp for nucleotide sequences comparison.
- BLATn for protein sequences comparison.
See the NCBI BLAST page for more details.
