Function

Reads and writes (returns) one set of sequences from many

Description

nthseqset writes to file a single sequence alignment (set) from an input stream of sequence sets. The sequence set is specified by number, which is the order it appears in the input file. The output file name may be specified.

Usage

Here is a sample session with nthseqset 


% nthseqset -osf phylip 
Reads and writes (returns) one set of sequences from many
Input sequence set(s): globins-all.phy
The number of the sequence set to output [1]: 2
output sequence(s) [globins-all.phylip]:

Input file format

nthseqset reads one or more nucleotiode 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 is the specified ordinal sequence set from the input USA.

In the example, the second sequence set from the input file will be written out to the specified output file.

Notes

In EMBOSS, when an application has to write out many sequences, they are typically all written to a single file. This default behaviour can be changed by using the qualifier -ossingle which forces each sequence to be written to its own file.

The program seqretsplit will take a file containing many sequences and will output many files, each containing one sequence. However you have no choice over the naming of the files - they are named after the ID name fo the sequence they contain.
