What are the parameters to use to limit the number of allignmets produced by blast for each query sequence?

I seem to remember it is '-b xxx' or something....

You are right, -b is the switch for blastall. Two relevant lines from blastall --help

  -v  Number of database sequences to show one-line descriptions for (V) [Integer]
    default = 500
  -b  Number of database sequence to show alignments for (B) [Integer]
    default = 250

BLAST ofspring

There is a large number of BLAST-like algorithms, trying to i.e. speed up the search by sacrificing sensitivity, or modify it to suit specific tasks, like genome-2-genome comparison. Before creating a separate page I will be dumping here such links *darked 07:39, 18 March 2010 (EDT):
