  36. **What it does**
    37. 

  37. 

  38. This tool converts every MAF block to a set of genomic intervals describing the position of that alignment block within a corresponding genome. Sequences from aligning species are also included in the output.
    39. 

  39. 

  40. The interface for this tool contains several options: 
    41. 

  41. 

  42.  * **MAF file to convert**. Choose multiple alignments from history to be converted to BED format.
    43. 

  43.  * **Choose species**. Choose additional species from the alignment to be included in the output 
    44. 

  44.  * **Exclude blocks which have a species missing**. if an alignment block does not contain any one of the species found in the alignment set and this option is set to **exclude blocks with missing species**, then coordinates of such a block **will not** be included in the output (see **Example 2** below).
    45. 

  45.  * **Remove Gap characters from sequences**. Gaps can be removed from sequences before they are output.
    46.

  111. **About formats**
    112. 

  112. 

  113. **MAF format** multiple alignment format file. This format stores multiple alignments at the DNA level between entire genomes. 
    114. 

  114. 

  115.  - The .maf format is line-oriented. Each multiple alignment ends with a blank line.
    116. 

  116.  - Each sequence in an alignment is on a single line.
    117. 

  117.  - Lines starting with # are considered to be comments.
    118. 

  118.  - Each multiple alignment is in a separate paragraph that begins with an "a" line and contains an "s" line for each sequence in the multiple alignment.
    119. 

  119.  - Some MAF files may contain two optional line types: 
    120. 

  120. 

  121.    - An "i" line containing information about what is in the aligned species DNA before and after the immediately preceding "s" line; 
    122. 

  122.    - An "e" line containing information about the size of the gap between the alignments that span the current block.
