Function

   Search for patterns in nucleotide sequences

Description

   fuzznuc searches for a specified PROSITE-style pattern in nucleotide
   sequences. Such patterns are specifications of a (typically short)
   length of sequence to be found. They can specify a search for an exact
   sequence or they can allow various ambiguities, matches to variable
   lengths of sequence and repeated subsections of the sequence. One or
   more nucleotide sequences are read from file. The output is a standard
   EMBOSS report file that includes data such as location and score of any
   matches.

Algorithm

   fuzznuc intelligently selects the optimum searching algorithm to use,
   depending on the complexity of the search pattern specified.

Command line arguments

Search for patterns in nucleotide sequences
Version: EMBOSS:6.5.6.0

   Standard (Mandatory) qualifiers:
  [-sequence]          seqall     Nucleotide sequence(s) filename and optional
                                  format, or reference (input USA)
   -pattern            pattern    The standard IUPAC one-letter codes for the
                                  nucleotides are used.
                                  The symbol 'n' is used for a position where
                                  any nucleotide is accepted.
                                  Ambiguities are indicated by listing the
                                  acceptable nucleotides for a given position,
                                  between square parentheses '[ ]'. For
                                  example: [ACG] stands for A or C or G.
                                  Ambiguities are also indicated by listing
                                  between a pair of curly brackets '{ }' the
                                  nucleotides that are not accepted at a given
                                  position. For example: {AG} stands for any
                                  nucleotides except A and G.
                                  Each element in a pattern is separated from
                                  its neighbor by a '-'. (Optional in
                                  fuzznuc).
                                  Repetition of an element of the pattern can
                                  be indicated by following that element with
                                  a numerical value or a numerical range
                                  between parenthesis. Examples: N(3)
                                  corresponds to N-N-N, N(2,4) corresponds to
                                  N-N or N-N-N or N-N-N-N.
                                  When a pattern is restricted to either the
                                  5' or 3' end of a sequence, that pattern
                                  either starts with a '<' symbol or
                                  respectively ends with a '>' symbol.
                                  A period ends the pattern. (Optional in
                                  fuzznuc).
                                  For example, [CG](5)TG{A}N(1,5)C
  [-outfile]           report     [*.fuzznuc] Output report file name (default
                                  -rformat seqtable)

Input file format

   fuzznuc reads in one or more nucleotide sequences.

   The input is a standard EMBOSS sequence query (also known as a 'USA').

   Major sequence database sources defined as standard in EMBOSS
   installations include srs:embl, srs:uniprot and ensembl

   Data can also be read from sequence output in any supported format
   written by an EMBOSS or third-party application.

   The input format can be specified by using the command-line qualifier
   -sformat xxx, where 'xxx' is replaced by the name of the required
   format. The available format names are: gff (gff3), gff2, embl (em),
   genbank (gb, refseq), ddbj, refseqp, pir (nbrf), swissprot (swiss, sw),
   dasgff and debug.

   See: http://emboss.sf.net/docs/themes/SequenceFormats.html for further
   information on sequence formats.

  Pattern specification

   Patterns for fuzznuc are based on the format of pattern used in the
   PROSITE database, with the difference that the terminating dot '.' and
   the hyphens, '-', between the characters are optional.

   The PROSITE pattern definition from the PROSITE documentation (amended
   to refer to nucleic acid sequences, not proteins) follows.
     * The standard IUPAC one-letter codes for the nucleotides are used.
     * The symbol `n' is used for a position where any nucleotide is
       accepted.
     * Ambiguities are indicated by listing the acceptable nucleotides for
       a given position, between square parentheses `[ ]'. For example:
       [ACG] stands for A or C or G.
     * Ambiguities are also indicated by listing between a pair of curly
       brackets `{ }' the nucleotides that are not accepted at a given
       position. For example: {AG} stands for any nucleotides except A and
       G.
     * Each element in a pattern is separated from its neighbour by a `-'.
       (Optional in fuzznuc).
     * Repetition of an element of the pattern can be indicated by
       following that element with a numerical value or a numerical range
       between parenthesis. Examples: N(3) corresponds to N-N-N, N(2,4)
       corresponds to N-N or N-N-N or N-N-N-N.
     * When a pattern is restricted to either the 5' or 3' end of a
       sequence, that pattern either starts with a `<' symbol or
       respectively ends with a `>' symbol.
     * A period ends the pattern. (Optional in fuzznuc).
     * All other characters, including spaces are not allowed.

   For example, in the EMBL entry J01636 you can look for the pattern:

[CG](5)TG{A}N(1,5)C


   This searches for "C or G" 5 times, followed by T and G, then anything
   except A, then any base (1 to 5 times) before a C.

   You can use ambiguity codes for nucleic acid searches but not within []
   or {} as they expand to bracketed counterparts. For example, "s" is
   expanded to "[GC]" therefore [S] would be expanded with a double set of
   brackets which is illegal.

   Note the use of X is reserved for proteins. You must use N for nucleic
   acids to refer to any base.

   The search is case-independent, so 'AAA' matches 'aaa'.

Output file format

   The output is a standard EMBOSS report file.

   The results can be output in one of several styles by using the
   command-line qualifier -rformat xxx, where 'xxx' is replaced by the
   name of the required format. The available format names are: embl,
   genbank, gff, pir, swiss, dasgff, debug, listfile, dbmotif, diffseq,
   draw, restrict, excel, feattable, motif, nametable, regions, seqtable,
   simple, srs, table, tagseq.

   See: http://emboss.sf.net/docs/themes/ReportFormats.html for further
   information on report formats.

   By default fuzznuc writes a 'seqtable' report file.
