 (version 4.11.2) (Bailey <em>et al.</em> 2009). For scanning genomes with the 
 BioPerl TFBS module, profiles were converted to PWMs and matches were kept with a 
 relative score &ge; 0.8. For the FIMO scan, profiles were reformatted to MEME motifs 
 and matches with a p-value &lt; 0.05 were kept. TFBS predictions that were not 
 consistent between the two methods (TFBS Perl module and FIMO) were removed. The 
 remaining TFBS predictions were colored according 
 to their FIMO p-value to allow for comparison of prediction confidence between 
 different profiles.</p>
