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

Query file

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


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

Query genetic code

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

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.
