+**What it does**
+
+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.
+
+The interface for this tool contains several options: 
+
+ * **MAF file to convert**. Choose multiple alignments from history to be converted to BED format.
+ * **Choose species**. Choose additional species from the alignment to be included in the output 
+ * **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).
+ * **Remove Gap characters from sequences**. Gaps can be removed from sequences before they are output.
+
+

+
+**Example 1**: **Include only reference genome** (hg18 in this case) and **include blocks with missing species**:
+
+For the following alignment::

+the tool will create **two** history items (one for hg18 and one for mm8) containing the following (**note** that both history items contain only one line describing the first alignment block. The second MAF block is not included in the output because it does not contain mm8):

+
+**About formats**
+
+**MAF format** multiple alignment format file. This format stores multiple alignments at the DNA level between entire genomes. 
+
+ - The .maf format is line-oriented. Each multiple alignment ends with a blank line.
+ - Each sequence in an alignment is on a single line.
+ - Lines starting with # are considered to be comments.
+ - 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.
+ - Some MAF files may contain two optional line types: 
+
+   - An "i" line containing information about what is in the aligned species DNA before and after the immediately preceding "s" line; 
+   - An "e" line containing information about the size of the gap between the alignments that span the current block.
