Sequence for shuffling or sequence-based probability distribution

            
        
Input sequence file        


            
        
Or paste a sequence (do not include definition line)
          
         

Are you shuffling a sequence?
            
Yes
       
No

If Yes, enter a sequence above, give the following two parameters and then
 

            
Number of sequences to generate (1 – 10000)     

            
Sequence line length in FASTA output (10 – 999)

            
            

Otherwise, choose a sequence type and base or amino acid probability distribution

          
          
Number of sequences to generate (1 – 10000)     

          
          
Sequence line length in FASTA output (10 – 999)

          
          
Sequence Length (10 – 4000)
