- **LAV format** LAV is an alignment format developed by Webb Miller's group at Penn State University. It is the primary output format for BLASTZ.

- **BED format** Browser Extensible Data format was designed at UCSC for displaying data tracks in the Genome Browser.

**Example**

- Convert LAV format::

    #:lav
    s {
      &quot;/galaxy/data/hg16/seq/chr19.nib&quot; 1 63811651 0 1
      &quot;/galaxy/data/mm5/seq/chr11.nib&quot; 1 121648857 0 1
    }
    h {
      &quot;> hg16.chr19&quot;
      &quot;> mm5.chr11 (reverse complement)&quot;
    }
    a {
      s 3500
      b 3001012 70568380
      e 3001075 70568443

      l 3008279 70573976 3008357 70574054 78
    }
    #:eof

- To two BED formatted files::

    chr19       3001011 3001075 hg16_0  0       +
    chr19       3008278 3008357 hg16_1  0       +
    
 **and**::
    
    chr11       70568379        70568443        mm5_0   0       +
