   QuickBLASTP is an accelerated version of BLASTP that is very fast and works best if the target percent identity is 50% or more. BlastP simply compares a protein query to a protein database. PSI-BLAST allows the user to build a PSSM (position-specific scoring matrix) using the results of the first BlastP run.

   17 mai 2017 · QuickBLASTP, an accelerated version of BLASTP, adds a new pre-processing step to the non-redundant (nr) protein database. In a matter of seconds, QuickBLASTP will find approximately 97% of the database sequences with 70% or more identity to your query and around 98% of the database sequence with 80% or more identity to your query.
