Function

   Mutate sequence beyond all recognition

Description

   This program changes a sequence a lot or a little, attempting to
   emulate various forms of mutation. You can set the number and types of
   mutations.

   It can act on the following sizes of sequence:
     * Point (single base or residue change)
     * Codon (not applicable in proteins)
     * Block of sequence (of a specified minimum and maximum random size)

   If the sequence is nucleic, the codon and block-sized operations can
   optionally be done in-frame. This causes the minimum block size to be
   set to 3 and the randomly chosen positions to be multiples of 3.

   For each of the above size of sequence it can produce the effects of
   any of the following types of mutation at a randomly chosen position:
     * Insertion of a randomly generated sequence
     * Deletion
     * Change (deletion then insertion of a random sequence of the same
       size)
     * Duplication at an adjacent position
     * Move region from one position to another (without deletion of the
       original)
     * Any of the above, chosen at random.
     * None of the above

   The input and output sequences may not differ if only a few changes
   are chosen as (for example) one in four nucleic acid point
   substitutions will not change the sequence.

   N.B. There is no selection of the types of mutation to produce viable
   sequence as there would be in a real organism. In particular, there is
   no attempt to bias mutations of nucleic acid sequences to conform to
   the C+G ratio in the sequence or to bias the codons in the direction
   of the frequencies used in the organism. This program emulates
   mutation, not selection.

   This program was named from the acronym of "Mutate Sequence Beyond All
   Recognition", by analogy with the acronym "fubar" commonly used in the
   US and UK armed forces.

Usage

   Here is a sample session with msbar

   This asks for 5 mutations, with point mutations as changes
   (substitutions), and the codon and block mutations ignored.

                                  5 (Duplications); 6 (Moves))
   -block              menu       [0] Types of block mutations to perform

                                  5 (Duplications); 6 (Moves))
*  -codon              menu       [0] Types of codon mutations to perform.
                                  These are only done if the sequence is
                                  nucleic. (Values: 0 (None); 1 (Any of the
                                  following); 2 (Insertions); 3 (Deletions); 4
                                  (Changes); 5 (Duplications); 6 (Moves))

                                  filename and optional format (output USA)

   Additional (Optional) qualifiers (* if not always prompted):
*  -inframe            boolean    [N] Do 'codon' and 'block' operations in
                                  frame

   Advanced (Unprompted) qualifiers:
   -othersequence      seqall     [asis:N] If you require that the resulting
                                  mutated sequence should not match a set of
                                  other sequences, then you can specify that
                                  set of sequences here. For example, if you
                                  require that the mutated sequence should not
                                  be the same as the input sequence, enter
                                  the input sequence here. If you want the
                                  result to be different to previous results
                                  of this program, specify the previous result
                                  sequences here. The program will check that
                                  the result does not match the sequences
                                  specified here before writing it out. If a
                                  match is found, then the mutation is started
                                  again with a fresh copy of the input
                                  sequence. If, after 10 such retries, there
                                  is still a match to the set of sequence
                                  given here, then the matching mutated
                                  sequence is written with a warning message.
   -minimum            integer    [1] Minimum size for a block mutation
                                  (Integer 0 or more)

                                  integer value)
