Function

Add a sequence reference (a full USA) to a list file

Description

yank adds the full Uniform Sequence Address (USA) of a specified sequence, or a region (subsequence) of a sequence, to a list file. The file is appended to by default but (optionally) is overwritten.A list file contains one or more sequence references (USAs). For example, a database entry, the name of a file containing sequences, or even the names of another list file. In addition to the name of the sequence, it can write the start and end position of a region within that sequence and, if the sequence is nucleic, if can specify whether the sequence is the reverse complement.

Usage

Here is a sample session with yank

This is an example of adding an entry for the part of tembl:x65921 between positions 1913 and 1915 to the existing list file 'cds.list':


% yank 
Add a sequence reference (a full USA) to a list file
Input (gapped) sequence: tembl:x65921
     Begin at position [start]: 1913
       End at position [end]: 1915
        Reverse strand [N]: 
List of USAs output file [x65921.yank]: cds.list

Input file format

yank reads a single nucleotide or protein sequence.

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.

You will be prompted for the start and end positions you wish to use.

If the sequence is nucleic, you will be prompted whether you wish to use the reverse complement of the sequence.

Output file format

Output files for usage example

File: cds.list

tembl-id:X65921[782:856]
tembl-id:X65921[951:1095]
tembl-id:X65921[1557:1612]
tembl-id:X65921[1787:1912]
tembl-id:X65921[1913:1915]

The output list file can now be read in by a program such as union by specifying the list file as '@cds.list' when union prompts for input.

Data files

None.

Notes

There are many ways of specifying input and output sequences for EMBOSS programs, including wildcarded sequence file names, wildcarded database entry names and list files. List files (files of file names) are the most flexible. Instead of containing the sequences themselves, a list file contains one or more sequence references (USAs). For example, a database entry, the name of a file containing sequences, or even the names of another list file. For example, here's a valid list file:

opsd_abyko.fasta
sw:opsd_xenla
sw:opsd_c*
@another_list

The file contains:

    * opsd_abyko.fasta - this is the name of a sequence file. The file is read in from the current directory.
    * sw:opsd_xenla - this is a reference to a specific sequence in the SwissProt database
    * sw:opsd_c* - this represents all the sequences in SwissProt whose identifiers start with ``opsd_c''
    * another_list - this is the name of a second list file 

Notice the @ in front of the last entry. This is the way you tell EMBOSS that this file is a list file, not a regular sequence file.

Without the program yank you would need to use a text editor such as pico to create the appropriate list files. yank makes this process easy.
