## Function

Sort sequences by size

## Description

sizeseq reads a set of sequences and sorts them by length. By default the sort is in ascending order.

## Usage

Here is a sample session with sizeseq

    % sizeseq -osformat swiss
    Sort sequences by size
    Input sequence set: globins.fasta
    Return longest sequence first [N]:
    output sequence(s) [globins.swiss]:
