Blast search

Enter sequence in FASTA format 


from Screen (cut & paste)...

from File:
Expectation value (E)
X dropoff value for gapped alignment (in bits) Alignment view options
Penalty for a nucleotide mismatch (blastn only) Filter query sequence
Number of one-line descriptions Cost to open a gap
Threshold for extending hits

Cost to extend a gap

Believe the query defline Show GI's in deflines
Word size Reward for a nucleotide match (blastn only)
Number of best hits from a region to keep Number of alignments to show
Effective length of the search space Perfom gapped alignment
Matrix Dropoff (X) for blast extensions in bits
Effective length of the database X dropoff value for final gapped alignment (in bits)
Use lower case filtering of FASTA sequence
