    Function
</H2>
Identify transcription factor binding sites in DNA sequences

<H2>
    Description
</H2>

<p><b>tfscan</b> scans one or more DNA sequences for transcription
factor binding sites from the TRANSFAC database.  The taxonomic group
(Fungi, Insects, ,Plants, Vertebrates or Other) is specified.  Matches
are searched for using fast sequence word-matching, optionally
allowing mismatches.  Because the binding sites are so small, there
will be many spurious (false positive) matches. Optionally, the
minimum length of a match to be reported may be specified.</p>

<p>An output file is written with information on the matches,
including sequence ID and accession number, the start and end
positions of the match in an input sequence and the sequence of the
region where a match has been found. Binding factor information, where
available, is given at the end of the matches for each matching
entry.</p>

    Input file format
</H2>

<b>tfscan</b> reads one or more nucleotide sequences.
<p>
<p>

The input is a standard EMBOSS sequence query (also known as a 'USA').

<p>
Major sequence database sources defined as standard in EMBOSS
installations include srs:embl, srs:uniprot and ensembl

<p>

Data can also be read from sequence output in any supported format
written by an EMBOSS or third-party application.

<p>
The input format can be specified by using the
command-line qualifier <tt>-sformat xxx</tt>, where 'xxx' is replaced
by the name of the required format.  The available format names are:
gff (gff3), gff2, embl (em), genbank (gb, refseq), ddbj, refseqp, pir
(nbrf), swissprot (swiss, sw), dasgff and debug.

<p>

See:

    Output file format
</H2>

<p>

The output is a standard EMBOSS report file. 

<p>

The results can be output in one of several styles by using the
command-line qualifier <tt>-rformat xxx</tt>, where 'xxx' is replaced
by the name of the required format.  The available format names are:
embl, genbank, gff, pir, swiss, dasgff, debug, listfile, dbmotif,
diffseq, draw, restrict, excel, feattable, motif, nametable, regions,
seqtable, simple, srs, table, tagseq.

<p>

See:
<A href="http://emboss.sf.net/docs/themes/ReportFormats.html">
http://emboss.sf.net/docs/themes/ReportFormats.html</A>
for further information on report formats.

<p>

<p>
By default the output is in 'seqtable' format.

<p>

The output consists of a title line then 5 columns separated by whitespace.

<p>

The first column is the identifier of the entry.

<p>

The second column is the Accession Number of the entry.

<p>

The third and fourth columns are the start and end positions of the
match in your input sequence.

<p>

The fifth column is the sequence of the region where a match has been found.

<p>

Binding factor information, where available, is given at the end
of the matches for each matching entry.



<H2>
    Data files
</H2>

<b>tfscan</b> reads the TRANSFAC SITE data held in the EMBOSS data files:
<p>
<ul>
<li>tffungi 
<li>tfinsect 
<li>tfplant 
<li>tfvertebrate 
<li>tfother
</ul>
<p>

Your EMBOSS administrator will have to run the EMBOSS program <b>tfextract</b>
in order to set these files up from the TRANSFAC distribution files.
<p>

<p>
EMBOSS data files are distributed with the application and stored
in the standard EMBOSS data directory, which is defined
by the EMBOSS environment variable EMBOSS_DATA.

<p>

To see the available EMBOSS data files, run:
<p>
<pre>
% embossdata -showall
</pre>
<p>
To fetch one of the data files (for example 'Exxx.dat') into your
current directory for you to inspect or modify, run:

<pre>

% embossdata -fetch -file Exxx.dat

</pre>
<p>

Users can provide their own data files in their own directories.
Project specific files can be put in the current directory, or for
tidier directory listings in a subdirectory called
".embossdata". Files for all EMBOSS runs can be put in the user's home
directory, or again in a subdirectory called ".embossdata".

<p>
The directories are searched in the following order:

<ul>
   <li> . (your current directory)
   <li> .embossdata (under your current directory)
   <li> ~/ (your home directory)
   <li> ~/.embossdata
</ul>
<p>


<H2>
    Notes
</H2>

<p>The TRANSFAC Database is a commercial database of eukaryotic cis-acting regulatory DNA elements and trans-acting factors. It covers the whole range from yeast to human.  The <tt>site.dat</tt> data file from TRANSFAC contains information on individual (putatively) regulatory protein binding sites. It has been divided into the following taxonomic groups.</p>
<ul>
<li>Fungi
<li>Insects
<li>Plants
<li>Vertebrates
<li>Other
</ul>
<p>An old public domain version of  TRANSFAC is available at: <a href="ftp://ftp.ebi.ac.uk/pub/databases/transfac/transfac32.tar.Z">ftp://ftp.ebi.ac.uk/pub/databases/transfac/transfac32.tar.Z</a></p>
