cusp |
Please help by correcting and extending the Wiki pages.
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.
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 and 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.
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:
| Program name | Description |
|---|---|
| cai | Calculate codon adaptation index |
| chips | Calculates Nc codon usage statistic |
| codcmp | Codon usage table comparison |
| codcopy | Copy and reformat a codon usage table |
| syco | Draw synonymous codon usage statistic plot for a nucleotide sequence |
