Monte Carlo operations

operation	resulting sequence
substitution of D at position 5	LGQIDTAE
insertion of D at position 5 with left shift	GQIWDTAE
insertion of D at position 5 with right shift	LGQIDWTA
deletion at position 5 with left shift	LGQITAED
deletion at position 5 with right shift	DLGQITAE

Valid Monte Carlo operations for input sequence s = LGQIWTAE (indexing starts with 1). In order to obtain sequences of the same length as s, in the case of a deletion a character (D) to be appended at the border has to be specified.
