<h3>Fasta output format</h3>

<h4>Question</h4>
When i tried to convert the EMBL format file into fasta format using the
program "<b>seqret</b>", I found that the Access.no appears twice...

<pre>
&gt;AF102796 AF102796 Homo sapiens alphaE-catenin (CTNNA1) gene, exon 11.

<h4>Answer</h4>

There are many "FASTA formats". EMBOSS uses the format that ACEDB and the
EBI genome projects use. The first field after the ID is the
accession number, so that accession numbers can be kept when sequences are
converted to FASTA format, without using the NCBI format (with '|'
characters in the IDs).
<p>

Your EMBL format file has IDs that look like accession numbers, so
EMBOSS fills in the accession number for each sequence, and reports it
in the FASTA format.
