55**Types of MAF to FASTA conversion**
56
57 * **Multiple Blocks** converts a single MAF block to a single FASTA block. For example, if you have 6 MAF blocks, they will be converted to 6 FASTA blocks.
58 * **One Sequence per Species** converts MAF blocks to a single aggregated FASTA block. For example, if you have 6 MAF blocks, they will be converted and concatenated into a single FASTA block.
59
60-------
61
62**What it does**
63
64This tool converts MAF blocks to FASTA format and concatenates them into a single FASTA block or outputs multiple FASTA blocks separated by empty lines.
65
66The interface for this tool contains two pages (steps):
67
68 * **Step 1 of 2**. Choose multiple alignments from history to be converted to FASTA format.
69 * **Step 2 of 2**. Choose the type of output as well as the species from the alignment to be included in the output.
70 
71   Multiple Block output has additional options:
72   
73   *  **Choose species** - the tool reads the alignment provided during Step 1 and generates a list of species contained within that alignment. Using checkboxes you can specify taxa to be included in the output (all species are selected by default).
74   *  **Choose to include/exclude blocks with missing species** - if an alignment block does not contain any one of the species you selected within **Choose species** menu and this option is set to **exclude blocks with missing species**, then such a block **will not** be included in the output (see **Example 2** below).  For example, if you want to extract human, mouse, and rat from a series of alignments and one of the blocks does not contain mouse sequence, then this block will not be converted to FASTA and will not be returned.

178**About formats**
179
180 **MAF format** multiple alignment format file. This format stores multiple alignments at the DNA level between entire genomes.
181
182 - The .maf format is line-oriented. Each multiple alignment ends with a blank line.
183 - Each sequence in an alignment is on a single line.
184 - Lines starting with # are considered to be comments.
185 - 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.
186 - Some MAF files may contain two optional line types:
187
188   - An "i" line containing information about what is in the aligned species DNA before and after the immediately preceding "s" line;
189   - An "e" line containing information about the size of the gap between the alignments that span the current block.
