BLAST Advanced Options


  -G  Cost to open a gap [Integer]
    default = 11
  -E  Cost to extend a gap [Integer]
    default = 1
  -e  Expectation value (E) [Real]
    default = 10.0
  -W  Word size, default is 11 for blastn, 3 for other programs.
  -v  Number of one-line descriptions (V) [Integer]
    default = 100
  -b  Number of alignments to show (B) [Integer]
    default = 100


  Limited values for gap existence and extension are supported for these three programs.  
  Some supported and suggested values are:

  Existence	Extension

     10             1
     10             2
     11             1
