[-calcfreq boolean] -outfile outfile [-zerocount boolean]
compseq -help
DESCRIPTION
compseq is a command line program from EMBOSS ("the European Molecular
Biology Open Software Suite"). It is part of the
"Nucleic:Composition,Protein:Composition" command group(s).
OPTIONS
Input section
-sequence seqall
-infile infile
This is a file previously produced by 'compseq' that can be used to
set the expected frequencies of words in this analysis. The word
size in the current run must be the same as the one in this results
file. Obviously, you should use a file produced from protein
sequences if you are counting protein sequence word frequencies,
and you must use one made from nucleotide frequencies if you are
analysing a nucleotide sequence.
Required section
-word integer
This is the size of word (n-mer) to count. Thus if you want to
count codon frequencies for a nucleotide sequence, you should enter
3 here. Default value: 2
Additional section
-frame integer
The normal behaviour of 'compseq' is to count the frequencies of
all words that occur by moving a window of length 'word' up by one
each time. This option allows you to move the window up by the
length of the word each time, skipping over the intervening words.
You can count only those words that occur in a single frame of the
word by setting this value to a number other than zero. If you set
it to 1 it will only count the words in frame 1, 2 will only count
the words in frame 2 and so on.
-ignorebz boolean
The amino acid code B represents Asparagine or Aspartic acid and
the code Z represents Glutamine or Glutamic acid. These are not
commonly used codes and you may wish not to count words containing
them, just noting them in the count of 'Other' words. Default
value: Y
-reverse boolean
Set this to be true if you also wish to also count words in the
reverse complement of a nucleic sequence. Default value: N
-calcfreq boolean
If this is set true then the expected frequencies of words are
calculated from the observed frequency of single bases or residues
in the sequences. If you are reporting a word size of 1 (single
bases or residues) then there is no point in using this option
because the calculated expected frequency will be equal to the
observed frequency. Calculating the expected frequencies like this
will give an approximation of the expected frequencies that you
might get by using an input file of frequencies produced by a
previous run of this program. If an input file of expected word
frequencies has been specified then the values from that file will
be used instead of this calculation of expected frequency from the
sequence, even if 'calcfreq' is set to be true. Default value: N
Output section
-outfile outfile
This is the results file.
-zerocount boolean
You can make the output results file much smaller if you do not
display the words with a zero count. Default value: Y

Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.
Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.
Free Software
Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.
Free Books
The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.
Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
Education
Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.
Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
