<td id="blast-threshold">The expectation value (E) threshold is a statistical measure of the number of expected matches in a random database. The lower the e-value, the more likely the match is to be significant. E-values between 0.1 and 10 are generally dubious, and over 10 are unlikely to have biological significance. In all cases, those matches need to be verified manually. You may need to increase the E threshold if you have a very short query sequence, to detect very weak similarities, or similarities in a short region, or if your sequence has a low complexity region and you use the "filter" option</td><p><a href='/help/sequence-searches' target='_top'>More...</a></p>E-Thresholdi

<td id="blast-matrix">The matrix assigns a probability score for each position in an alignment. The BLOSUM matrix assigns a probability score for each position in an alignment that is based on the frequency with which that substitution is known to occur among consensus blocks within related proteins. BLOSUM62 is among the best of the available matrices for detecting weak protein similarities. The PAM set of matrices is also available. If "Auto" is set, the matrix will be selected depending on the query sequence length.</td><p><a href='/help/sequence-searches' target='_top'>More...</a></p>Matrixi

<td id="blast-filter">Low-complexity regions (e.g. stretches of cysteine in <a href="http://www.uniprot.org/uniprot/Q03751">Q03751</a>, or hydrophobic regions in membrane proteins) tend to produce spurious, insignificant matches with sequences in the database which have the same kind of low-complexity regions, but are unrelated biologically. If "Filter low complexity regions" is selected, the query sequence will be run through the program SEG, and all amino acids in low-complexity regions will be replaced by X's. </td><p><a href='/help/sequence-searches' target='_top'>More...</a></p>Filteringi

<td id="blast-gapped">This will allow gaps to be introduced in the sequences when the comparison is done.</td><p><a href='/help/sequence-searches' target='_top'>More...</a></p>Gappedi

<td id="blast-numal">Limits the number of returned alignments.</td><p><a href='/help/sequence-searches' target='_top'>More...</a></p>Hitsi
