Format must be FASTA: >your_description
ATGCATGC... the nucleic sequence (16S, 23S will come soon)

OR #Genus_species:

for exemple #Methanothermus_sociabilis. Note that BLAST may not return all relevant sequences.

Paste the query here (or ? or help) then proceed to the next step

The default DB Contains Type Material (RT or T flag) and or, if missing a selected representative sequence of the species. These sequences are selected on their quality and representativity.

The use of a the complementary DB has been removed from the workflow.

Results will not be conserved for more than 8 hours, if needed please download your working directory
