## Function

Mutate a sequence

## Description

This program changes a sequence, attempting to emulate various forms of mutation. It reads one or more sequences and writes an output file with with a set of (mutated) sequences. The number, size and type of mutation may be specified.

## 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.

      [-sequence]          seqall     Sequence(s) filename and optional format, or
                                      reference (input USA)

                                      (Values: 0 (None); 1 (Any of the following);

    *  -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))
      [-outseq]            seqoutall  [.] Sequence set(s)
                                      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)
       -maximum            integer    [10] Maximum size for a block mutation (Any
                                      integer value)

The output is a sequence file with 5 substitutions relative to the original sequence.

## Data files

None.

## Notes

The qualifiers allow the number, size and type of mutation to be controlled.

The "size" of mutation may be set as following:

- 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.

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.

If you require the mutated sequences to not match some other set of sequences, this set may be specified with the -othersequence qualifier. For example, the mutants should not match the input sequence, or the results of a previous run of this program. msbar ensures the mutants do not match the specified sequences. 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.
