Check the nucleotide database(s) to search. The list of available databases depends on the team your account is a member of.

Database genetic code

Genetic code to use for translating the nucleotide database into protein.

Query file

Upload file containing query protein sequence(s) in FASTA format.


Query protein sequence(s) in FASTA format. This data is used only if no file is specified in the field above.

SEG filter

Filter out low-complexity regions from the query sequence.

E-value required

Expectation value threshold.

Output format required

Format of search results.

# seq descriptions

Number of one-line descriptions to show in the output.

# alignments

Number of alignments to show in the output.
