Function

   Reads and writes (returns) sequences

Description

   seqret reads in one or more sequences and writes them out again. The
   sequence input may be a literal sequence or read from a database, file,
   file of sequence names, or even the command-line or the output of
   another programs. The sequence output can be written to screen, to
   file, or passed to another program. A wide range of standard sequence
   formats may be specified for input and output. If you don't specify the
   input format, seqret will try a set of possible formats until it reads
   it in successfully. The sequence input and output, as for all EMBOSS
   programs, is described by a Uniform Sequence Address. This is is a very
   flexible way of specifying one or more sequences from a variety of
   sources and includes sequence files, database queries and external
   applications.

   There are many options built-in into EMBOSS for detailed specification
   of the input and output sequences, for example the sequence type, file
   format. specification of sequence regions by begin and end positions,
   or generation of the reverse complement of a nucleic acid sequence. On
   output seqret can change the case of the sequence to upper or to lower
   case.

   seqret is useful for a variety of tasks, including extracting sequences
   from databases, displaying sequences, reformatting sequences, producing
   the reverse complement of a sequence, extracting fragments of a
   sequence, sequence case conversion or any combination of the above
   functions.

Usage

   Here is a sample session with seqret

   Extract an entry from a database and write it to a file:


% seqret
Reads and writes (returns) sequences
Input (gapped) sequence(s): tembl:x65923
output sequence(s) [x65923.fasta]:


   Go to the input files for this example
   Go to the output files for this example

   Example 2

   Read all entries in the database 'tembl' that start with 'ab' and write
   them to a file. In this example the specification is all done in the
   command line and to stop Unix getting confused by the '*' character, it
   has to have a backslash ('\') before it:


% seqret "tembl:ab*"  aball.seq
Reads and writes (returns) sequences


   Go to the output files for this example

   Example 3

   seqret does not read in features by default because this results in
   slightly faster performance. If however you wish to read in features
   with your sequence and write them out on output, using '-feature' will
   change the default behaviour to use any features present in the
   sequence. N.B. use embl format for the output file as the default
   format 'fasta' reports the features in gff (file "<seqname>.gff")


% seqret -feature
Reads and writes (returns) sequences
Input (gapped) sequence(s): tembl:x65923
output sequence(s) [x65923.fasta]: embl::x65923.embl


   Go to the output files for this example

   Example 4

   Display the contents of the sequence on the screen:


% seqret
Reads and writes (returns) sequences
Input (gapped) sequence(s): tembl:x65923
output sequence(s) [x65923.fasta]: stdout

Input file format

   seqret reads one or more nucleotide or protein 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.

Output file format

   The output is a standard EMBOSS sequence file.

   The results can be output in one of several styles by using the
   command-line qualifier -osformat 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,
   excel, feattable, motif, nametable, regions, seqtable, simple, srs,
   table, tagseq.

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

   The output from seqret is one or more sequences, and by default will be
   written in FASTA format.

   If the '-firstonly' qualifier is used then only the first sequence of
   the input USA specification will be written out.

   In some cases the output filename will be the same as the input
   filename, but as seqret reads only the first sequence before opening
   the output file it may try to overwrite the input. Note that this is
   not true of seqretset which reads all sequences into memory at startup,
   but which can need a large amount of memory for many sequences.

Notes

   This description of what you can do when reading or writing files is
   not specific to the program seqret. All EMBOSS programs that read or
   write sequences can do the same.

   seqret is often one of the first programs taught in EMBOSS training
   courses. This is because it is versatile, it is extremely powerful for
   its size (17 lines of code) it illustrates many aspects of EMBOSS
   programs and it was one of the first EMBOSS programs to be written, so
   it has a special place in the hearts of EMBOSS developers.

   The name 'seqret' derives both from its function ("sequence return")
   and from the fact that immense amounts of functionality can come from
   so few lines of source code - most of the work is done by the EMBOSS
   libraries which the program calls and whose complexity is hidden, or
   "secret".

   The simplicity of the above description of this program greatly
   understates the rich functionality of this program.

   Because EMBOSS programs can take a wide range of qualifiers that
   slightly change the behaviour of the program when reading or writing a
   sequence, this program can do many more things than simply "read and
   write a sequence".

   seqret can read a sequence or many sequences from databases, files,
   files of sequence names, the command-line or the output of other
   programs and then can write them to files, the screen or pass them to
   other programs. Because it can read in a sequence from a database and
   write it to a file, seqret is a program for extracting sequences from
   databases. Because it can write the sequence to the screen, seqret is a
   program for displaying sequences.

   seqret can read sequences in any of a wide range of standard sequence
   formats. You can specify the input and output formats being used. If
   you don't specify the input format, seqret will try a set of possible
   formats until it reads it in successfully. Because you can specify the
   output sequence format, seqret is a program to reformat a sequence.

   seqret can read in the reverse complement of a nucleic acid sequence.
   It therefore is a program for producing the reverse complement of a
   sequence.

   seqret can read in a sequence whose begin and end positions you have
   specified and write out that fragment. It is therefore a utility for
   doing simple extraction of a region of a sequence.

   seqret can change the case of the sequence being read in to upper or to
   lower case. It is therefore a simple sequence beautification utility.

   seqret can do any combination of the above functions.

   The sequence input and output specification of this (and many other
   EMBOSS programs) is described as being a Uniform Sequence Address.

   The Uniform Sequence Address, or USA, is a somewhat tongue-in-cheek
   reference to a URL-style sequence naming used by all EMBOSS
   applications.

   The USA is a very flexible way of specifying one or more sequences from
   a variety of sources and includes sequence files, database queries and
   external applications.

   See the full specification of USA syntax at:
   http://emboss.sourceforge.net/docs/themes/UniformSequenceAddress.html

   The basic USA syntax is one of:
     * "file"
     * "file:entry"
     * "format::file"
     * "format::file:entry"
     * "database:entry"
     * "database"
     * "@file"

   Note that ':' separates the name of a file containing many possible
   entries from the specific name of a sequence entry in that file. It
   also separates the name of a database from an entry in that database

   Note also that '::' separates the specified format of a file from the
   name of the file. Normally the format can be omitted, in which case the
   program will attempt to identify the correct format when reading the
   sequence in and will default to using FASTA format when writing the
   sequence out.

   Valid names of the databases set up in your local implementation of
   EMBOSS can be seen by using the program 'showdb'.

   Database queries, and individual entries in files that have more than
   one sequence entry, use wildcards of "?" for any character and "*" for
   any string of characters. There are some problems with the Unix shell
   catching these characters so they do need to be hidden in quotes or
   preceded by a backslash on the Unix command line, (for example
   "embl:hs\*")

   The output USA name 'stdout' is special. It makes the output go to the
   device 'standard output'. This is the screen, by default.

  Example USAs

   The following are valid USAs for sequences:

   USA Description
   xxx.seq A sequence file "xxx.seq" in any format
   fasta::xxx.seq A sequence file "xxx.seq" in fasta format
   gcg::egmsmg.gcg A sequence file "egmsmg.gcg" in GCG 9 format
   egmsmg.gcg -sformat=gcg A sequence file "egmsmg.gcg" in GCG 9 format
   embl::x13776.em A sequence file "x13776.em" in EMBL format
   embl:x13776 EMBL entry X13776, using whatever access method is defined
   locally for the EMBL database
   embl:K01793 EMBL entry K01793, using whatever access method is defined
   locally for the EMBL database and searching by accession number and
   entry name (K01793 is a secondary accession number in this case for
   entry J01636)
   embl-acc:K01793 EMBL entry X13776, using whatever access method is
   defined locally for the EMBL database and searching by accession number
   only
   embl-id:x13776 EMBL entry x13776, using whatever access method is
   defined locally for the EMBL database, and searching by ID only
   embl:v0029* EMBL entries V00290, V00291, and so on, usually in
   alphabetical order, using whatever access method is defined locally for
   the EMBL database
   embl or EMBL:* All sequences in the EMBL database
   @mylist Reads file mylist and uses each line as a separate USA. This is
   standard VMS list file syntax, also used in SRS 4.0 but missing in SRS
   5.0 onwards. The list file is a list of USAs (one per line). List files
   can contain references to other lists files or any other standard USA.
   list::mylist Same as "@mylist" above
   'getz -e [embl-id:x13776] |' The pipe character "|" causes EMBOSS to
   fire up getz (SRS) to extract entry x13776 from EMBL in EMBL format.
   Any application or script which writes one or more sequences to stdout
   can be used in this way.
   asis::atacgcagttatctgaccat So far the shortest USA we could invent. In
   'asis' format the name is the sequence so no file needs to be opened.
   This is a special case. It was intended as a joke, but has proved quite
   useful for generating command lines when testing.

  Input sequence formats

   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.

  Output sequence formats

   The output is a standard EMBOSS sequence file.

   The results can be output in one of several styles by using the
   command-line qualifier -osformat 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,
   excel, feattable, motif, nametable, regions, seqtable, simple, srs,
   table, tagseq.

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

  Future directions

   More formats, both for input and for output, can be easily added, so
   suggestions are always welcome.

  Associated qualifiers

   As noted previously there are many 'associated' qualifiers that alter
   the behaviour of seqret when it reads in or writes out a sequence. As
   these are used in all EMBOSS programs that read in or write out
   sequences, they are not reported by the '-help' qualifier. They are
   however reported by the pair of qualifiers: '-help -verbose':

   Some of the more useful associated qualifiers are:

   Qualifier                      Description
   -sbegin   The first position to be used in the sequence
   -send     The last position to be used in the sequence
   -sreverse Use the reverse complement of a nucleic acid sequence
   -sask     Ask the user for begin/end/reverse information
   -slower   Convert the sequence to lower case
   -supper   Convert the sequence to upper case
   -sformat  Specify the input sequence format
   -osformat Specify the output sequence format
   -ossingle Write each entry into a separate file

   The set of associated qualifiers for sequences behave in different ways
   depending on where they appear.

   If these qualifiers immediately follow a parameter they apply only to
   that parameter and not to all cases. If they occur before any
   parameters, they apply to all following sequence parameters.

   If there are no two parameters of equal type, the order of parameters
   and their qualifiers is irrelevant.

   Where a qualifier is defined more than once, for example "-sformat" for
   2 input sequences to be aligned, the qualifier name can have a number
   to indicate which sequence is meant. "-sbegin2=25" will apply only to
   the second sequence, no matter where it appears on the command line.

   The -sbegin and -send qualifiers take an integer number specifying the
   position to begin or end reading a sequence. If the number is positive,
   the number is the position counting from the first base or residue of
   the sequence. If the number is negative the position is counted from
   the end of the sequence, so position -1 is the last base or residue of
   the sequence. (If -sbegin 0 is used, it is assumed to be the same as
   -sbegin 1 and -send 0 is the same as -send -1.)

   The filter qualifier makes the program behave like a filter, reading
   its (first) input 'file' from the standard input, and writing its
   (first) output 'file' to the standard output. The -filter qualifier
   will also invoke the -auto qualifier, so the user is never prompted for
   any missing values.

   Example:

% cat sequence.seq | seqret -filter | lpr


   The example shows the application seqret being run with the -filter
   qualifier. The input file is 'piped' into the program using the unix
   command cat and the output is 'piped' directly to the unix program lpr,
   which will print it on the printer.

   When the -options qualifier is used and not all the parameters are
   given on the command line, it will query the user for those parameters.
   It will not only query the user for the required parameters as it would
   do without the -options qualifier, but it will also query the user for
   the optional parameters.

   When the -stdout qualifier is used, the user will still be prompted for
   all the info that is required, but will write to standard output by
   default. The user will also still be prompted for an output filename,
   in case the user wants to save the output to a file.

  Fasta output format

    Question

   When i tried to convert the EMBL format file into fasta format using
   the program "seqret", I found that the Access.no appears twice...

>AF102796 AF102796 Homo sapiens alphaE-catenin (CTNNA1) gene, exon 11.

    Answer

   "It is not a bug ... it is a feature"

   There are many "FASTA formats". EMBOSS uses the format that ACEDB and
   the EBI genome projects use. The first field after the ID is the
   accession number, so that accession numbers can be kept when sequences
   are converted to FASTA format, without using the NCBI format (with '|'
   characters in the IDs).

   Your EMBL format file has IDs that look like accession numbers, so
   EMBOSS fills in the accession number for each sequence, and reports it
   in the FASTA format.
