Learn to use FASTA, a web-based tool for finding sequence similarities for proteins and nucleic acids. FASTA, one of the fastest sequence algorithms, optimizes searches for local alignments using a substitution matrix. Users can select their own parameters (or simply use the default choices) to find the best matches to their sequence. Results are displayed with alignments, scores, and visual graphics to help interpret the results. Sequences are also linked to annotated databases to provide additional biological knowledge.

Algorithms and Analysis : This category contains various tools that may help perform analysis of different genomics data types. This may include sequence alignment, large-scale or complex queries, motif finding, or comparative assessments.
Tip of the Week: File Format conversion: Many of us have worked with DNA and protein sequences of course in several different formats: GenBank and FASTA to name two broadly used ones, but there are many others. Different tools and databases w...
