shuffleseq

 

Function

Shuffles a set of sequences maintaining composition

Description

This takes a sequence as input and outputs one or more sequences whose order has been randomly shuffled. No bases or residues are changed, only their order.

The number of shuffled sequences output can be set by the '-shuffle' qualifier.

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:mmam
Output sequence [mmam.fasta]:
