Toolkit. Search Tools CS-BLAST is an extension to standard NCBI BLAST that allows to increase its sensitivity by a factor of more than two on remote homologs at the same speed.
CS-BLAST first adds context-specific pseudocounts to the input sequence and then jumpstarts PSI-BLAST with the resulting profile. The output is identical to BLAST and contains a list of closest homologs with alignments. PDB.
