Input file format

descseq 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.

File: dna.text

ACGTACGTACGTACGTACGTACGTACGTACGTACGTACGTACGTACGTAC
GTACGTACGTACGTACGTACGTACGTACGTACGTACGTACGTACGTACGT

Output file format

descseq writes the sequence file with a changed name or description.

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.

Notes

Most sequence formats allow, at the very minimum, a name for the sequence and some comments to be stored in the sequence file. descseq let's you change the sequence name and / or description, and is far more convenient and less error-prone than using the editor for editing.

The default action is to replace the existing name or description with your new one, but by using the qualifier -append what you enter is appended to the existing name or description. Note that if you append to a description, no space is inserted by default bewteen the existing description and your appended text. You have to put in a space yourself if you require one.

Diagnostic Error Messages

Exit status

It always exits with status 0.
