NAME

gp_cusage - print codon usage of sequence(s)

SYNOPSIS

gp_cusage [-c table_file ] [-p] [-q] [-v] [-d] [-h] [-?] [inputfile] [outputfile]

OPTIONS

-c table_file
Uses alternate codon table.
-p
Nicely prints the codon table & exits gracefully.
-v
Prints the version information.
-d
Prints lots of debugging information.
-h
Shows usage information.
inputfile
file to proces; if not given, will use standard input
outputfile
file to write the data to; if not given, will use standard output

DESCRIPTION

gp_cusage sources one or more DNA or RNA sequence files and prints the total percentual frequencies of all codons. The sequences have to begin with a start codon, but if they are incomplete (i.e. end before the stop codon is read) only a warning is issued.

EXAMPLES

o
to print the codon usage of the fasta sequences contained in the file orfs.fasta, type
gp_cusage orfs.fasta
o
to print the codon usage of a protein sequence located at genome positions 15843 14602 in the sequence Mpneu.fasta, type
getseq 15843 14602 Mpneu.fasta | gp_cusage

DIAGNOSTICS

All Genpak programs complain in situations you would also complain, like when they cannot find a sequence you gave them or the sequence is not valid.

The Genpak programs do not write over existing files. I have found this feature very useful :-)

BUGS

I'm sure there are plenty left, so please mail me if you find them. I tried to clean up every bug I could find.
