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
