For certain purposes NO sequence set is required. By default Pure Random sequence set is generated.
Sequences with linear distribution between ATGC will be generated. Length and number of sequences are keep.
In each sequence a nucleotids are swapped in random manner. Length, number and ATGC proportion in sequences are keep.
Between sequences in same position a nucleotids are swapped in random manner. Length and number of sequences are keep.
Nucleotids are Random swaping between different positions and different sequences. Length and number of sequences are keep.
