その他オプション
より詳細な設定を行いたい場合、パラメータを直接入力してください。
指定が可能なオプションは以下のとおりです。
オプションの前には"-"(マイナス)を置き、各パラメータはスペースで区切って下さい。
例) -G 2 -E 1 -q -2
G => Cost to open a gap [Integer] default=0 (zero invokes default behavior)
E => Cost to extend a gap [Integer] default=0 (zero invokes default behavior)
X => X dropoff value for gapped alignment (in bits) [Integer] default=0 (zero invokes default behavior)
y => Dropoff (X) for blast extensions in bits (0.0 invokes default behavior) [Real] default = 0.0
I => Show GI's in deflines [T/F] default=F
q => Penalty for a nucleotide mismatch (blastn only) [Integer] default=-3
r => Reward for a nucleotide match (blastn only) [Integer] default=1
v => Number of database sequences to show [Integer] default=500
f => Threshold for extending hits, default if zero [Integer] default=0
g => Perfom gapped alignment [T/F] (NA with tblastx) default=T
D => DB Genetic code (for tblast[nx] only) default=1
J => Believe the query defline [T/F] default=F
W => Word size, default if zero [Integer] default=0
z => Effective length of the database [Real] default=0 (use zero for the real size)
n => MegaBlast search [T/F] default = F
A => Multiple Hits window size (zero for single hit algorithm) [Integer] default = 40
L => Location on query sequence [String] Optional
Z => X dropoff value for final gapped alignment (in bits) [Integer] default = 0
U => Use lower case filtering of FASTA sequence [T/F] Optional default = F
S => Query strands to search against database (for blast[nx], and tblastx). 3 is both, 1 is top, 2 is bottom [Integer] default = 3
D => DB Genetic code (for tblast[nx] only) [Integer] default = 1
K => Number of best hits from a region to keep (off by default, if used a value of 100 is recommended) [Integer] default = 0
P => 0 for multiple hits 1-pass, 1 for single hit 1-pass, 2 for 2-pass [Integer] default = 0
Y => Effective length of the search space (use zero for the real size) [Real] default = 0
S => Query strands to search against database (for blast[nx], and tblastx) 3 is both, 1 is top, 2 is bottom [Integer] default = 3
A => Multiple Hits window size, default if zero (blastn/megablast 0, all others 40 [Integer] default = 0
t => Length of the largest intron allowed in tblastn for linking HSPs (0 disables linking) [Integer] default = 0

Q => Query Genetic code to use [Integer] default=1
e => Expectation vaule [Real] default=10.0
F => Filter query sequence [String] (DUST with blastn, SEG with others) default=T
w => Frame shift penalty (OOF algorithm for blastx) [Integer] default = 0
M => Matrix [String] default=BLOSUM62
