Function

   Shuffles a set of sequences maintaining composition

Description

   shuffleseq reads one or more sequences and writes them out again in a
   random (shuffled) order. The number of shuffles may be specified. Only
   the order of sequences is changed, no bases or residues are changed.

Usage

   Here is a sample session with shuffleseq

   This makes two randomised copies of the input sequence:


% shuffleseq -shuffle 2 
Shuffles a set of sequences maintaining composition
Input sequence(s): tembl:L48662
output sequence(s) [l48662.fasta]:
