rmes.composition
Length and Word Composition of a Given DNA Sequence



Description Usage Options Output Examples Availability


Description


This program displays the length of a DNA sequence and the counts of words of a given length; the phase can be taken into account.
The DNA sequence should be given in
a specific format.

Usage


rmes.composition  -seq DNA-sequence-file
                 [-phase] 
                 [-hmin <hmin>] [-hmax <hmax>]
                 [-eng[lish]]

Options

-seq:
This option introduces the name of the input DNA sequence file.
-phase
When set, the phase (or reading frame) is taken into account.
The phase of a letter (base) in the sequence corresponds to its position in the sequence modulo 3. A given base can be in phase 1, 2 or 3. The phase of a given word in the sequence is defined to be the phase of its last letter in the sequence.
-hmin <hmin>, -hmax <hmax>
<hmin> introduces the minimal length of the words to be counted (by default, 1) and <hmax> the maximal length (by default <hmin>).
-eng[lish]
When set, the messages are in english.
By default, they are in french.
