- BLAST+ executables — BLASTHelp documentation
The NCBI provides a suite of command-line tools to run BLAST called BLAST+ This allows users to perform BLAST searches on their own server without size, volume and database restrictions
- Needleman-Wunsch alignment of two nucleotide sequences - BLAST
Local alignments algorithms (such as BLAST) are most often used A global alignment should only be used on sequences that share significant similarity over most of their extents, and then it will sometimes return a better presentation
- Frequently Asked Questions — BLASTHelp documentation
You can expand a cluster on your BLAST results to view and download a report or the sequences of all member proteins, and you can also perform a BLAST alignment of all the members of the cluster
- BLAST Highlights
The links in the Basic BLAST section of the Home tab lead to BLAST forms that share a common design Each form has four sections (examples are from nucleotide BLAST):
- Overview — ElasticBLAST 1. 5. 0 documentation
The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches
