Blastp - compares an amino acid query sequence against a
protein sequence database.
Blastn - compares a nucleotide query sequence against a
nucleotide sequence database.
Blastx - compares the six-frame conceptual translation
products of a nucleotide query sequence (both
strands) against a protein sequence database.
tBlastn - compares a protein query sequence against a
nucleotide sequence database dynamically
translated in all six reading frames (both
strands).
tBlastx - compares the six-frame translations of a
nucleotide query sequence against the six-frame
translations of a nucleotide sequence database.
For blastx 1st sequence should be nucleotide, tblastn 2nd sequence nucleotide.

Expectation value
|
Sets the threshold expectation value for keeping alignments.
This is the E from the Karlin-Altschul equation that describes how often an alignment with a given score is expected to occur at random.
