    38 <h3>Introduction</h3>
 | 
| 
 | 
    39 <p>
 | 
| 
 | 
    40 Codonlogo is based on <a href="http://weblogo.berkeley.edu/">WebLogo</a>,a web based application designed to make the 
 | 
| 
 | 
    41 generation of sequence logos easy and painless.CodonLogo Extends Weblogo to allow generation of sequence logos with codons rather than amino acids or nucleotides.
 | 
| 
 |

 | 
    44 <p>
 | 
| 
 | 
    45 <a href="http://www.lecb.ncifcrf.gov/~toms/sequencelogo.html">Sequence logos</a> are a graphical representation of an amino acid
 | 
| 
 | 
    46 or nucleic acid multiple sequence alignment developed by 
 | 
| 
 | 
    47 <a href="http://www.lecb.ncifcrf.gov/~toms/schneider.html">Tom Schneider</a>
 | 
| 
 | 
    48  and <a href="http://www.lecb.ncifcrf.gov/~toms/sipinfo.html">Mike
 | 
| 
 | 
    49  Stephens</a>.
 | 
| 
 | 
    50 Each logo consists of stacks of symbols, one stack for each position in the
 | 
| 
 | 
    51 sequence. The overall height of the stack indicates the sequence conservation
 | 
| 
 | 
    52 at that position, while the height of symbols within the stack indicates the
 | 
| 
 | 
    53 relative frequency of each codon at that position. In general,
 | 
| 
 | 
    54 a sequence logo provides a richer and more precise description of, for example,
 | 
| 
 | 
    55 a binding site, than would a consensus sequence.
