Other Ways to Retrieve Similar Sequences

At NCBI:

• Related sequences option in the Entrez Nucleotides, Proteins, and Structures databases
• BLink
• other BLAST programs (PSI-BLAST, PHI-BLAST, MegaBLAST, BLAST against genomes, etc)
• CD-Search (demo in next slide) and CDART

Outside of NCBI:

• Other, modified versions of BLAST (e.g., WU-BLAST)
• other similarity searching algorithms such as FASTA and Smith-Waterman
