                                   cusp 



Function

   Create a codon usage table

Description

   Reads one or more coding sequences (CDS sequence only) and calculates
   a codon frequency table.

   The output file can be used as a codon usage table in other
   applications.

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.


% cusp -sbeg 135 -send 1292 
Create a codon usage table
Input nucleotide sequence(s): tembl:paamir

   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.

   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.

   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.

   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, 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.

   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
