Before running &prog; you will need to obtain a comparison file. 
&prog; supports three different comparison file formats:

          <PARA>
The <COMMAND>blastall</COMMAND> command must be run with the <COMMAND>-m
8</COMMAND> flag which generates one line of information per HSP. If 
<ULINK URL="http://blast.ncbi.nlm.nih.gov/">BLAST+</ULINK>
is used then the legacy_blast.pl PERL script (bundled along with the BLAST+ applications)
can be used to generate the tabular format or run it with the <COMMAND>-outfmt 6</COMMAND> flag.

       Anthony Underwood and Jonathan Green at the <ULINK URL="http://www.hpa.org.uk/">
       Health Protection Agency</ULINK> have developed an online tool, <ULINK

       ACT comparison files.

       Also there is <ULINK URL="http://www.webact.org/">WebACT</ULINK> which was

TYPE="external"><LITERAL>big_blast.pl</LITERAL></ULINK> to run blast and
generate a file of results in MSPcrunch format.  To run this script you will
need to install a copy of the Pathogen Sequencing Unit <ULINK

sequence name, subject sequence start, subject sequence end, subject sequence
name.

  <SECT1 ID="RUNNINGUNIX">
    <TITLE>Running &prog; on UNIX and GNU/Linux Systems</TITLE>
    <PARA>
On Unix and GNU/Linux the easiest way to run the program is to run the script
called <COMMAND>act</COMMAND> in the &prog; installation directory (see <XREF
LINKEND="INSTALLATION">) like this:
    </PARA>

    <PARA>
      <COMMAND>~/act/act</COMMAND>
    </PARA>

    <PARA>
If all goes well you will be presented with a small window with one menu (the
File menu).  See <XREF LINKEND="LAUNCH-WINDOW"> for a description of this
window.
    </PARA>

    <PARA>
Alternatively you start &prog; with the names of two sequence/EMBL/GENBANK
files and a file containing the comparison data eg:
    </PARA>

    <PARA>
      <COMMAND>
~/act/act sequence1 blast_output.crunch sequence2
      </COMMAND>
    </PARA>

    <PARA>
If you have more than two sequences (there is no upper limit) they should be
listed on the command line separated by the corresponding comparison file:
    </PARA>

    <PARA> 
      <COMMAND>
~/act/act sequence1 seq2_v_seq1.crunch sequence2 seq3_v_seq2.crunch sequence3 
      </COMMAND>

See <XREF LINKEND="UNIXARGS"> for a list of the other possible command line
arguments.

doesn't work for you:

If you select this menu item a file requester will be displayed which allows
you to open the sequence files and the comparison files.  If the files you
select are read successfully, a new window will open, which shows the

out how to use the main window.  The comparison file is described in <XREF
