Function
</H2>
Create a codon usage table
<H2>
Description
</H2>
Reads one or more coding sequences (CDS sequence only) and calculates
a codon frequency table.
<p>
The output file can be used as a codon usage table in other applications.
<H2>
Usage
</H2>
<b>Here is a sample session with cusp</b>
<p>
This example uses only one input sequence. The normal use would be to use a set of coding sequences as the input.

<p>
The example usage read in a
single CDS from Pseudomonas aeruginosa which has a very high GC
content ands a strong coding bias, as shown by the codons for Alanine
where those ending with G or C are used almost exclusively.
<p>
The 'Fract' column gives that proportion of usage of a given codon among
its redundant set (i.e. the set of codons which code for this codon's amino
acid). For example, the sum of the 6 codons representing serine will
add up to 1.00.
<p>
The /1000 column represents the number of codons, given the
input sequence(s), there are per 1000 bases. This will be an
extrapolation if the sequence is shorter than 1000 bases.
<p>
If multiple sequences are input then the statistics are given for all of
the sequences together, not individually.

Data files
</H2>
cusp reads a codon usage file, but only as a template and does not use
any of the data so any codon usage file from any species will give the
same results.
<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>
