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.

Command line arguments

   Standard (Mandatory) qualifiers (* if not always prompted):
  [-sequence]          seqall     Sequence(s) filename and optional format, or
                                  reference (input USA)
   -count              integer    [1] Number of times to perform the mutation
                                  operations (Integer 0 or more)
   -point              menu       [0] Types of point mutations to perform
                                  (Values: 0 (None); 1 (Any of the following);
                                  2 (Insertions); 3 (Deletions); 4 (Changes);
                                  5 (Duplications); 6 (Moves))
   -block              menu       [0] Types of block mutations to perform
                                  (Values: 0 (None); 1 (Any of the following);
                                  2 (Insertions); 3 (Deletions); 4 (Changes);
                                  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))
  [-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)

                                  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.
