| skipseq

## Function

Reads and writes (returns) sequences, skipping the first few

## Description

skipseq skips the first few sequences in a multiple set of sequences, and writes out the rest of them.

skipseq is a variant of the standard program for reading and writing sequences, seqret.

seqret has an option to allow it to only read the first sequence from a multiple set of sequences (-firstonly). seqret cannot, however, skip the first few sequences from a multiple set of sequence, writing out the rest; this is what skipseq is for.

In all other respects, skipseq is the same as seqret.

## Usage

Here is a sample session with skipseq

This does not skip any sequences. It is exactly equivalent to seqret:

    % skipseq
    Reads and writes (returns) sequences, skipping the first few
    Input sequence(s): tembl:eclac*
    Number of sequences to skip at start [0]:
    Output sequence [eclac.fasta]:

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

Example 2

This skips the first input sequence, writing out the others:

    % skipseq -skip 1
    Reads and writes (returns) sequences, skipping the first few
    Input sequence(s): tembl:eclac*
    Output sequence [eclac.fasta]:

Go to the output files for this example

## Input file format

skipseq reads one or more sequence USAs.

### Input files for usage example

'tembl:eclac*' is a sequence entry in the example nucleic acid database 'tembl'

See the documentation for seqret to see the full range of things that you can do when reading and writing sequences.

## Output file format

skipseq writes one or more sequences files, having optionally skipped the first few sequences.

See the documentation for seqret to see the full range of things that you can do when reading and writing sequences.

## Data files

None.

## Notes

None.

## References

None.

## Warnings

You may skip all of the input files.
If the -skip value is greater than or equal to the number of input sequences, there is no warning: this is legal.

## Diagnostic Error Messages

None.

## Exit status

It always exits with status 0.
