PSI-BLAST - EMBL-EBI
PSI-BLAST allows users to construct and perform a NCBI BLAST search with a custom, position-specific, scoring matrix which can help find distant evolutionary relationships. Users can …
Protein BLAST: search protein databases using a protein query
PSI-BLAST allows the user to build a PSSM (position-specific scoring matrix) using the results of the first BlastP run. PHI-BLAST performs the search but limits alignments to those that match …
