Function

   Create a codon usage table from nucleotide sequence(s)

Description

   cusp calculates a codon usage table for one or more nucleotide coding
   sequences and writes the table to file.

   The codon usage table gives for each codon: i. Sequence of the codon.
   ii. The encoded amino acid. iii. The proportion of usage of the codon
   among its redundant set, i.e. the set of codons which code for this
   codon's amino acid. iv. The expected number of codons, given the input
   sequence(s), per 1000 bases. v. The observed number of codons in the
   input sequences.

Usage

   Here is a sample session with cusp

   This example uses only one input sequence. The normal use would be to
   use a set of coding sequences as the input.

   The example shown reads 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.

   The columns are as follows: i. "Codon" (sequence of the codon). ii.
   "AA" (the encoded amino acid). iii. "Fraction" (the proportion of
   usage of the codon among its redundant set, i.e. the set of codons
   which code for this codon's amino acid). iv. "Frequency" (the expected
   number of codons, given the input sequence(s), per 1000 bases). This
   will be an extrapolation if the sequence is shorter than 1000 bases.
   v. "Number" (the observed number of codons in the input sequences).

   If multiple sequences are input then the statistics are given for all
   of the sequences together, not individually.

Data files

   cusp reads a codon usage file as a template for it's output file. The
   data in this table is ignored entirely. This functionality is
   hard-coded and invisible to the user.

   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.

   To see the available EMBOSS data files, run:

% embossdata -showall

   To fetch one of the data files (for example 'Exxx.dat') into your
   current directory for you to inspect or modify, run:

% embossdata -fetch -file Exxx.dat

   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".

   The directories are searched in the following order:
     * . (your current directory)
     * .embossdata (under your current directory)
     * ~/ (your home directory)
     * ~/.embossdata
