== Identification ==&lt;br /&gt;
Files will often start with a header line (though this is technically optional), such as &amp;lt;code&amp;gt;@HD VN:1.6 SO:coordinate&amp;lt;/code&amp;gt;, where the VN parameter gives the version number of the format and this may be followed with a SO or G0 parameter giving sorting order or grouping of alignments.&lt;br /&gt;
