BLAT
====
BLAT is a bioinformatics software a tool which performs rapid mRNA/DNA and cross-species protein alignments. 

blat (version: v340)- Standalone blat sequence search command line tool. 
-------------------------------------------------------------------------

usage:
++++++

  $ blat database query [-ooc=11.ooc] output.psl

where:
   database and query are each either a .fa, .nib or .2bit file,
   or a list of these files with one file name per line.
   -ooc=11.ooc tells the program to load over-occurring 11-mers from
   an external file.  This will increase the speed
   by a factor of 40 in many cases, but is not required.
   output.psl is the name of the output file.
