Please choose the parameters for BLAST. The most important parameters are the database and of course the sequence. Other parameters can probably be left at their default values.

If you want to use the result of your blast search to download aligned sequences from our database you must select either one of the SSU or LSU databases but not both. Furthermore you must set the alignment view to "pairwise".

To go easy on our server you can only start one BLAST at a time.

Program: ( -p option)
Database: ( -d option)
Expect value: ( -e option)
Gap opening cost: ( -G option)
Gap extention cost: ( -E option)
max. score dropoff value (bits): ( -X option)
Mismatch penalty: ( -q option)
Match reward: ( -r option)
Word size: ( -W option)
Alignment view: ( -m option)
Number of one-line descriptions: ( -v option)
Number of alignments: ( -b option)
Output mode: ( -T option)
Query sequence: Enter your sequence below in fasta format or as raw text (anything that is not a letter will be stripped out). Only one sequence please, if you enter more than one sequence they will be concatenated and be treated as one sequence. Please limit your query to a maximum of 10000 nucleotides.
