## Function

Remove a section from a sequence

## Description

This simple editing program allows you to cut out a region from your sequence by specifying the begin and end positions of the region to remove. It removes the sequence from the specified start to the end positions (inclusive) and writes the remaining sequence to the output file.

## Usage

Here is a sample session with cutseq

To remove bases 10 to 12 from a database entry and write to the new sequence file 'gatta2.seq':

    % cutseq tembl:x13776 gatta2.seq -from=10 -to=12
    Remove a section from a sequence

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

Example 2

To remove the first 20 bases from 'tembl:x13776' and write it to 'jsh.seq':

    % cutseq tembl:x13776 -from=1 -to=20 -out=jsh.seq
    Remove a section from a sequence

Go to the output files for this example

Example 3

If the default start and end positions are accepted, then all of the sequence is removed!

    % cutseq tembl:x13776 starta.seq -sbeg=-1000 -send=1290
    Remove a section from a sequence
    Start of region to delete [1168]:
    End of region to delete [1290]:

## Input file format

cutseq 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.

## 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.

## Data files

None.

## Notes

Qualifiers that are in-built for sequence datatypes allow the input and output files to be specified in more detail, for example, the format for the output files.

## References

None.

## Warnings

You can delete a complete sequence and write out an empty sequence file.

## Diagnostic Error Messages

None.

## Exit status

It always exits with status 0

## Known bugs
