Function

Write to file a subset of an input stream of sequences

Description

notseq writes to file a subset of an input stream of sequences. The list of sequence names or accession numbers to exclude from output is provided as a string. Optionally, the excluded sequences are also written to file.

Usage

Here is a sample session with notseq

In this case the excluded sequences (myg_phyca and lgb2_luplu) are not saved to any file: 


% notseq 
Write to file a subset of an input stream of sequences
Input (gapped) sequence(s): globins.fasta
Sequence names to exclude: myg_phyca,lgb2_luplu
output sequence(s) [hbb_human.fasta]: mydata.seq

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

Example 2

Here is an example where the sequences to be excluded are saved to another file: 


% notseq -junkout hb.seq 
Write to file a subset of an input stream of sequences
Input (gapped) sequence(s): globins.fasta
Sequence names to exclude: hb*
output sequence(s) [hbb_human.fasta]: mydata.seq

Go to the output files for this example

   Standard (Mandatory) qualifiers:
  [-sequence]          seqall     (Gapped) sequence(s) filename and optional
                                  format, or reference (input USA)
  [-exclude]           string     Enter a list of sequence names or accession
                                  numbers to exclude from the sequences read
                                  in. The excluded sequences will be written
                                  to the file specified in the 'junkout'
                                  parameter. The remainder will be written out
                                  to the file specified in the 'outseq'
                                  parameter.
                                  The list of sequence names can be separated
                                  by either spaces or commas.
                                  The sequence names can be wildcarded.
                                  The sequence names are case independent.

Input file format

notseq 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.

The names (or accession numbers) of the sequences to be excluded can be entered as a file of such names by specifying an '@' followed by the name of the file containing the sequence names. For example: '@names.dat'.

The names or accession numbers of the sequences to be excluded are not standard EMBOSS USAs. Only the ID name or accession number can be specified, you cannot specify the sequences as 'database:ID', 'file:accession', 'format::file', etc.

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.

Notes

notseq was written for the case where a file containing several sequences was being used as a small database, but some of the sequences were no longer required. notseq splits the input sequences into those that you wish to keep and those you wish to exclude.

Wildcarded names and accession numbers may be specified in the input string by using *.

The names (or accession numbers) of the sequences to be excluded can be entered as a file of such names by specifying an @ followed by the name of the file containing the sequence names. For example: @names.dat.

References

None.

Warnings

The input string does not support the full USA syntax; only the name or accession number should be specified, not the database or file that these entries may occur in.

Diagnostic Error Messages

If no matches are found to any of the specified sequence names, the message "This is a warning: No matches found." is displayed.

Exit status

It exits with a status of 0 unless no matches are found to any of the input sequences name, in which case it exits with a status of -1.

Known bugs

None.
